Making an Ancient Greek Lyre for my Classics Independent Study

Sabrina Farrell sitting on the quad with the ancient Greek lyre that she built.Echoes of the ancient Greek chelys lyre kept appearing in my courses: Greek pottery depicting a lyrist’s playing technique or ancient literature describing its acoustics. These sources inform our knowledge of the lyre, and can in turn be brought to life by attempting to replicate the lyre itself. Endeavoring to experience the music of the ancient world this winter study, I worked with the Williams College Makerspace, Classics department, and many other incredible sources of help to create a playable, sonorous chelys lyre replica.

The First Vegan Lyre… Ever??

My completed ancient Greek lyre sounds amazing!

My completed ancient Greek lyre sounds amazing!

The ancient Greek chelys lyre, named so for the χέλυς (tortoise) shell used for the soundbox resonator, is said in the Homeric Hymn to Hermes to have first been made by Hermes as an apology gift to Apollo for kidnapping his cows. This was one of the ancient Greek texts I read with my project’s advisor, Visiting Assistant Professor of Classics Marissa Henry, who was an incredible guide throughout the entire project. Reading about the unfortunate tortoise who was first turned into a lyre, I was very glad about my choice to make a fully vegan lyre—no tortoises or cows harmed! In fact, in all my research I did not come across another chelys lyre—ancient or modern—that uses zero animal products. This gave a lot of room for creativity, riffing off of the trial and error of other lyre-makers.

Tortoiseshell Soundbox

The biggest headscratcher was the tortoiseshell soundbox, which we considered making out of a hollowed-out gourd or a wooden salad bowl. While both are great alternatives, a gourd is quite fragile and unpredictable as a natural object, and a salad bowl felt too easy. Luckily, the Makerspace gives students access to 3D-printers for just this sort of moment. When I asked David Keiser-Clark, the Manager of the Makerspace and FabLab, and a huge contributor to the lyre, if it was possible to 3D print the tortoiseshell, I expected it to be too complicated or not viable—perhaps the material wouldn’t be resonant enough, or a tortoiseshell too complex to print. It turned out to be a fantastic way to replicate the tortoiseshell, using an online 3D scan of a tortoiseshell that I downloaded (as an STL file) and then modified using Fusion 360 and Blender (modeling software) to create strategic holes for the arms of the lyre to enter and the tailpiece to jut out.

Help from an Expert Luthier

Next, we had to think about how to build the drumhead of the lyre, usually made by stretching animal skin over the face of the shell. In my research, mylar came up as an alternative, but mylar is not flexible and mouldable in the same way that animal skin is. I learned this and many other luthier insights from Steve Sauvé at Sauvé Guitars in North Adams, Massachusetts. He presented me with an alternative: a mylar banjo head! We decided to fashion it to the lyre by 3D modeling and printing a bespoke insert ring that would snugly support the banjo head, forming the face of the lyre. In the original hymn, the strings of the lyre were made from the guts of Apollo’s cow, and gut strings were primarily used for traditional instruments. For our purposes, nylon proved a great alternative, with ukulele strings being the best fit, which I found with the help of Collar City Guitars in Troy, NY.

And Alumni Woodworkers

Using a bandsaw to cut one of the lyre’s arms.

Shaping the wood for the lyre was tough to figure out and presented challenges. I had never used power or carving tools, and I was starting from two gorgeous blocks of cherry wood bought from Sauvé Guitars. I learned how to shape and replicate the traditional snaking arms and intricate tuning bulges (these hold the strings and allow them to be adjusted) from the advice of the teachers (all alumni: Seth Rolland, Chris Mullen, and Richard Song) of the winter study course “Introduction to Woodwork: Art, Design and Craft” (WSP 16). They were incredibly helpful, showing me how to safely use a bandsaw to create rough, blocky cuts for the arms and bridge. I called this the “Minecraft version” of the lyre. 

Learning to Use a Wood Lathe

Jason Mativi, Senior Science Center Shop Engineer, and David Keiser-Clark were both huge resources who together helped me learn how to safely use the wood lathe and disc sander.

Jason Mativi, Senior Science Center Shop Engineer, and David Keiser-Clark were both huge resources who together helped me learn how to safely use the wood lathe and disc sander.

The intimidating wood lathe in the Hopper Science Shop was the key to rounding the rectangular crossbars and tuning bulges (pegs) that maintain the tension of the lyre’s seven strings. Jason Mativi, Senior Science Center Shop Engineer, and David Keiser-Clark were both huge resources who together helped me learn how to safely use these tools. David stayed with (always alert) throughout the entire process, offering me a kind balance of support, guidance, and independence.

The lathe was the tool I had to be the most cautious while operating: it spins the wood very rapidly (~2000 RPM) and I used lathe chisels to slowly transform the rough cut block of cherry into a gorgeous cylindrical object with uniform shape and width. I used the lathe to create two crossbars and 14 wood tuning bulges, then used a stationary disc sander to further shape these pieces and add intentional charring to increase visual contrast. I learned how to use a universal metal bender to shape a stock 3/16” straight metal steel rod into a functional “buckle” that I later mounted in the lyre’s tail (below the bridge) and used to tie off the strings.

Spokeshaves and Flowing Organic Curves

David and I returned to the Makerspace, and he introduced me to using high-quality spokeshaves (like two-handed wood planes) to shape the arms: they pull the wood off in super-thin and satisfying ribbons that result in a smoothly curved and organic shape. 

However, when I began the dry assembly of these nearly completed pieces, it became apparent that the length of the lyre’s arms were too short to allow for tying off the strings below the 8” banjo head. The lyre required a longer tail. Ack! I brought this problem to David and he suggested using a leftover scrap (from our original cherry planks) to create a contoured half-lap woodworking joint to seamlessly extend the arms. I was running out of time, and he volunteered to do this complicated hand work. He returned it to me the next day and I was able to resume the dry assembly.

3D Modeling: The Magic of Creating Custom Shapes and Bespoke Parts

The next challenge was to figure out how to securely connect the 3D printed tortoiseshell with the two cherry arms. A shoutout to Anderson Keiser-Clark, 13, for contributing his Blender expertise that modified the digital tortoiseshell to include snug holes for the arms and tail to pass through. He also created a custom lid that bolts to the base (to allow future maintenance) and included a ring on which to securely mount the banjo head. 

3D modeling work with Blender software created exactly matching top and bottom parts that securely hold the arms in place.

I used a coping saw to shape the bridge and create the desired curves. I stained only the 14 tuning bulges, and then used vegan Walrus oil on all of the wood parts to bring out the beautiful highlights of the grain. And finally, I successfully assembled the lyre and tuned the strings. Amazing!

Learning to Play the Lyre

In order to learn the physical technique of playing the lyre, Dr. Henry and I made our way to Vermont to meet with members of the Call of Kinnaru, a group from the University of Vermont who play new ancient music featuring kitharists among other instrumentalists. Professor John Franklin and Rachel Fikes were kind enough to let me play their lyres and introduce me to the incredible process of developing music from what we know of ancient practices. It was especially enriching to physically hold a lyre, so that I could feel exactly what I was working towards.

Inspiration from the New York City Ballet

The symbol of the New York City Ballet Company is the lyre.

Even outside making the lyre, I got to experience the joy of this instrument in many ways. Artist-in-Residence in Dance Janine Parker, whom I have been learning ballet with since I first came to Williams, took three of us to the New York City Ballet, since the symbol of the New York City Ballet Company is the lyre. Not only that, but it featured a dance called Antique Epigraphs choreographed by Jerome Robbins to music by Claude Debussy, which was an incredible piece inspired by Greek antiquity. This was such an incredible ballet to see and a singularly amazing experience in seeing the ancient embodied.

This independent study also offered me the opportunity to make mini cardboard lyres with 6th grade students from Williamstown Elementary School’s Robotics program, led by Associate Professor of Classics Sarah Olsen. The theme this year for the robotics competition was archaeology! I was so happy to share with them my journey building a lyre and the exercise making cardboard lyres. They are such amazing students and are lucky to work alongside Professor Olsen who first introduced me to ancient Greek language and classics as a whole.

Thank You!

Thank you to everyone already mentioned and all the many others who helped me along the way! This was truly a group effort to build and I’m so thankful for the incredible support in making music.

Starting point was a slab of cherry wood (arms drawn in pencil). Final product is my own custom ancient Greek lyre that is an absolute joy to play!

My senior theater thesis Hamletmachine #2026 requires precision in props—a collection of objects tied to the ensemble performers’ family and political histories. The adaptation thus lives at the intersection of the personal and the historical.

The Makerspace was instrumental in this process. My team and I were looking for a replica of Lenin’s head in bronze, but the performer who had a personal association with it couldn’t bring one from home, and we couldn’t find one online. David from the Makerspace helped with modeling, adjustments, 3D printing, and we discussed types of paint that would adhere to the resultant PLA printed head. Ultimately, I used a metallic bronze acrylic paint as a post-processing medium to transform the white plastic head into a vivid and almost iridescent sculptural replica of Lenin’s head for the show.

Building a Mirrorhaploscope: When Psychology Meets the Makerspace

Introduction

An early iteration of the Mirrorhaploscope. before additional horizontal tracks were added for increased maneuverability.

An early iteration of the Mirrorhaploscope. before additional horizontal tracks were added for increased maneuverability.

Most people think vision is simple. You open your eyes and see. The new mirrorhaploscope in Assistant Professor Kim Wong’s lab proves it is much more complicated. This past fall, Professor Wong reached out to the Williams Makerspace with a request that would merge research, design, and hands-on building: a mirrorhaploscope for studying how the brain chooses what we see. The device will be used in both PSYC 300 (Perception) and the WAVE Lab (Wong Attention, Vision, and Encoding Lab), supporting studies of visual awareness, attention, and binocular rivalry. The collaboration made it possible for students to help construct a fully functional research instrument that they will later use in their own experiments.

The Problem or Research Purpose

A mirrorhaploscope is a deceptively simple optical instrument with powerful implications. It allows researchers to present different images to each eye at the same time—allowing us to push our visual system to its limits, and test unconscious, automatic processing. With this setup, Professor Wong can run Continuous Flash Suppression (CFS) experiments, a method that consists of overwhelming one eye with a chaotic, rapidly flashing pattern (aka a “dynamic Mondrian mask”),  while the other sees a stable image. This flashing is so overwhelming to the visual system that it completely dominates awareness, and the brain temporarily “suppresses” the stable image. Experimenters then measure the amount of time it takes for the stable image to finally “break through” the suppression from the flashing pattern.

In plain terms? The device lets researchers peek into how attention and perception works while the participant themselves has no idea that there is even another image present at all.  This allows them to ask the critical question: “What does your visual system do automatically, before you’re even conscious of it?” They can thus experimentally manipulate: 

  • What kinds of images capture visual awareness first (i.e. which images “break through” the suppression faster)?
  • What kinds of stimuli or scenes are unconsciously prioritized by the visual system?
  • How does the brain resolve conflicting visual input?
  • Why do we notice some things instantly while completely missing others?
  • Do we find major differences across individuals’ visual processing?  

And all of this comes from four mirrors angled just right.

The Build

The build started with a brainstorming meeting mid September. Professor Wong explained the necessary features: tilt-adjustable mirrors, a full height-adjustment track so the device could fit all necessary setups, and a touch of aesthetics. That became our blueprint. 

A 3D sketch of the mirrorhaploscope before diving into tangible build

From there, the making process unfolded like a narrative. First came the wooden frame for mirror mounts, then choosing hardware that allowed fine-tuned rotation, and testing a series of height adjustments designs. Decisions about height adjustability required a universal T-track system, while the mirror tilt demanded ball-and-socket mounts with tightening knobs.

Along the way, the build team had plenty of human moments: 

  • Attaching the mirrors came with a number of attempts, including failure to account for how quickly the glue solidified, and coordination between team members became essential.
  • During one clean up session, the force of the vacuum was not accounted for and a wooden piece made its way down the pipe. Disassembling the vacuum was required to retrieve the piece. 
  • The team was so focused on protecting the first set of mirrors from getting scratched that it was not until final assembly that we realized the mirrors were in fact distorted and new ones must be ordered.

By early November, after careful alignment and many hours in the woodshop, the mirrorhaploscope finally took shape.

The Final Product

The finished mirrorhaploscope is clean, sturdy, and deceptively elegant. 

It features: 

  • Four angled mirrors arranged to separate left-eye and right-eye images 
  • Adjustable mirror mounts using ball-and-socket heads for precise tilting 
  • Two independent height and width adjustable track systems to accommodate different setups and users 

It can sit on a standard 30-inch table, with the mirror heights adjustable to match Professor Wong’s required visual angles. It is mobile enough to be deployed in both the PSYC 300 classroom and the WAVE Lab, where it will support experiments for years to come. 

When the team handed it to Professor Wong, the feeling was unanimous: proud, relieved, and a little in awe that a pile of wood, mirrors, and hardware had become a fully functional research tool.

Why This Project Matters

This project represents something bigger than a Makerspace build. We didn’t just learn about visual perception, we helped create the instrument that will produce new scientific knowledge. The Makerspace enabled academic experimentation, allowing psychology, engineering, and creativity to intersect in a single device. 

And now, PSYC 300 students will do something rare in an undergraduate course: use a professional research device they helped design and build. The mirrorhaploscope is more than a tool; it’s proof that hands-on learning can quite literally change how we see. This project didn’t just teach us about perception. It taught us that learning accelerates when students build the tools that drive discovery.

Making Time: Reimagining Ancient Greek Paradigms through 3D Printing

ChatGPT-generated image of Chronos and symbols of linearized time such as the hourglass and clock gears

For the final project of my Winter Study course, COGS 10: Minds, Machines, and the Making of Meaning taught by Dr. Charles Kaufmann, I was asked to “integrate the scientific, philosophical, computational, and experiential strands of the course into a single, coherent act of meaning-making.” Having recently read an article about bioprinting—a form of 3D printing that uses organic matter, often including living cells, to create new tissue—I was inspired to cap off my learning experience with some form of material creation.

A simple Google search of “Williams 3D printing” led me to the Makerspace, the on-campus hub for all things related to innovation, creativity, and hands-on learning. I was particularly moved by the idea of Critical Making which combines critical thinking and material design into a unified mode of expression and inquiry. I knew this was how I wanted to approach my culminating reflection.

Minds and Machines Behind the Project

The crux of my project was to explore how minds and machines interface to create meaning, specifically through the lens of different ancient Greek models of time as represented by three deities: Chronos, Aion, and Kairos. That process of intellectual discovery was enabled by the following:

Minds and Machines Behind the Project

Getting to Know the Space

At the outset of the project, I lacked confidence, having no prior training in 3D modeling of any kind. When I reached out to Mr. David to talk through the specifics of my project idea and gauge the possibility of its completion in a compressed timeframe, I feared that my inexperience would make my goals unfeasible. On my first tour of the Makerspace a few days later, however, my trepidation was quickly melted away by Mr. David’s nonpareil enthusiasm and encouragement. I was pleasantly surprised to hear that my idea was realistically achievable, that he would help through the entire process, and that I could learn first-hand to perform some of the techniques involved.

Final Thoughts

Collaborating with the Makerspace was incredible! With the zealous help of Mr. David, I was able to transform my project idea into a reality in about one week. Creation has never felt so possible. I would encourage anybody and everybody to visit the Makerspace. You never know when immersing yourself in a new environment and connecting with the experts and student workers involved will spark the desire to make something new. While every creative endeavor has a unique set of technical demands, ranging in complexity, getting started really is as simple as dropping by during Open Hours or sending a friendly email. I found this process enriching, fun, and informative, and I will definitely be working with the Makerspace team again soon.

Rust, Patina, and Star Wars: Playing with Copper-Infused PLA

A photo of the copper infused PLA printed Benchy before the oxidization process.

What if your 3D prints could age like ancient artifacts? That was the question I asked myself when I got my hands on a spool of copper-infused PLA. Unlike ordinary plastic filaments, this one behaves a little more like metal: it shines, it scratches differently, and, best of all, it rusts.

With a little kitchen chemistry (just vinegar and table salt), I discovered that you can accelerate corrosion and grow that gorgeous blue-green patina we usually see on old copper roofs or statues. Suddenly, a simple 3D Benchy boat looked like it had been dredged up from a shipwreck… or stolen from a galaxy far, far away.

The Secret Weapon: A New Nozzle

During the submersion, the copper failed to oxidize in the vinegar and salt solution because there was no oxygen available.

During the submersion, the copper failed to oxidize in the vinegar and salt solution because there was no oxygen available.

Before the fun part (corroding things), there’s the practical problem: copper filament is brutal on regular brass nozzles. They get chewed up fast, and I didn’t want to spend my weekends endlessly recalibrating.

So, I splurged on an E3D V6 1.75mm Nozzle, a hardened steel nozzle disguised as brass in its heat performance. At $21, it wasn’t exactly cheap, but it meant I could use a variety of filaments, including abrasive ones, without damaging the nozzle. So I can still print fast, but will have less maintenance.  In other words, more time experimenting, less time swearing at the printer.

Painting with Chemistry

The 3D Benchy boat after (correctly) using a spray bottle (vinegar, water, salt) to initiate the oxidization process.

I started with the classic test print: a 3DBenchy boat.

I mixed up my “magic potion”, vinegar plus salt until it wouldn’t dissolve anymore. I submerged the boat in the solution and left it for two days and… nothing happened. I realized that oxidation requires air. So I set it on a tray and sprayed the boat every couple of hours with a cheap misting bottle. A bit of oxidation occurred but it was underwhelming. I experimented and used 220 grit sandpaper to smooth some edges and surfaces of the benchy. I gave it the same corrosion treatment, and waited. Within hours, tiny blue crystals nucleated across its surface like frost on glass. My theory is that sanding exposed more of the copper embedded in the PLA material. Now, each cost of spray deepened the effect and dried differently depending on where the misted liquid pooled, dripped, or got caught on overhangs.

Slowly, the hull blossomed with patches of turquoise and jade crystals. After four days of experimenting, flipping, spraying, and waiting, I finally had my masterpiece: a lost, sunken ship.  The edges shimmered like oxidized jewelry, while the lip of the hull turned into a miniature science experiment in evaporation. It felt like I was less “finishing a print” and more “collaborating with chemistry.”

It looked ancient, precious, and heavy with story. The corrosion process didn’t just coat the print,  it transformed it into something that felt alive, growing, and shifting with each spray. Under natural light, the patina was subtle; under LEDs, it glowed like a relic.

Who knew that a bit of vinegar, salt, and patience could turn plastic into treasure?

This project reminded me why I love tinkering: sometimes it’s not about controlling every detail, but about letting the materials surprise you. Copper PLA, a new nozzle, and some kitchen chemistry turned my prints into artifacts that could belong in a museum. And what’s really exciting about this test is that it is another tool the Makerspace has for projects with faculty or students.

And honestly? I’ll never look at table salt the same way again.

Stuffed Cats and Stubborn Needles: A Beginner Sewing Workshop

The goal of this workshop was to have participants (a total of 8 people attended) learn basic sewing and cutting skills through the process of making a small stuffed cat. We started out by picking colors for our felt and thread, and then I instructed students how to thread a needle and sew on eyes. This part seemed to be the most challenging for people who have never sewn before, as threading a needle can be frustrating, and figuring out how to properly sew buttons can be a bit tricky. But after this step, everyone seemed much more comfortable and required less induction on how to sew both sides of the felt together. 

Success: Everybody Made One

There was an option to attach a keychain to the stuffy, which some people chose.

Since attaching the keychain can be challenging, I took the lead, giving a detailed explanation of what I was doing. By the end of the workshops, all participants were able to make at least one stuffy, with a few making more than one. We’re hoping to do another sewing session soon, maybe expanding beyond cats to other animals or characters based on participant suggestions. I’m hoping next time we get returning participants who enjoyed the community-building aspect of the workshop.

A Piece of Fall on Your Desk: Making Wire Trees in the FabLab

It’s autumn in the Berkshires, and the hillsides have transformed into a living mosaic of yellow, orange, and red. Every bend in the road feels like a painting. It’s the kind of season that makes you slow down and breathe deeply, and that invites reflection and creativity alike. As the temperatures drop and daylight shortens, people naturally turn toward warm, tactile projects, something to do indoors while still feeling connected to the changing world outside.

Inside the FabLab at Williams, the tables were covered with coils of copper wire, bowls of fall-colored beads, and smooth palm-sized rocks gathered from nearby paths. Students filled the space, laughing, chatting, and ready for some creativity. More than a crafting session, it was a moment of community. Some students designed these fall wire tree centerpieces as gifts for friends or family, and others planned to display theirs on desks or windowsills, a reminder of the Berkshires’ fleeting colors. 

Examples of the completed wire trees.

Examples of the completed wire trees.

To get started, you need only a few simple tools: a ruler, a rock, a pair of wire cutters, hot glue, and of course, plenty of wire and beads. It’s helpful to measure and cut the wire strands ahead of time to about 5 inches per strand. 

The process of creating a fall wire tree centerpiece begins quite simply with the rock. The base grounds the wire tree. A flat, stable rock works best, especially since the finished tree can grow unexpectedly heavy once adorned with dozens of beads. The balance of weight and width matters: you want the stone to hold the span of the tree’s branches so that the sculpture stands upright.

Once the base is chosen, the creativity begins. You start from the ground up, forming the roots, then the trunk, and finally the branches. When it comes time to form the trunk, a bit of strength is required. You twist multiple boughs together, compressing them into a single sturdy column. It’s worth studying real tree forms or even looking at reference photos online to understand how trunks curve and how roots flare out. This reminder of how art is connected with ecology is part of an idea called biomimicry, the study of how nature’s solutions inspire sustainable human innovation (to read more, see the Biomimicry Institute here).

Once the trunk is done, it helps to focus on the primary branches, and then the smaller offshoots. After that comes the most time-consuming but perhaps most rewarding step: adding the foliage. Every bead must be threaded, secured, and adjusted, one at a time. Each leaf cluster begins by threading a bead onto a wire strand and looping it in place, twisting the ends together to secure it. It is meditative work. Some students in the FabLab played quiet music as they worked, and others chatted about classes or what they did on Mountain Day. 

Twisting the roots around the rock is the next step, and though it is not always visible in the final display, it’s vital to the sculpture’s integrity. After securing the tree to its base, students used a bit of hot glue to hold the tree down, then gave it one last round of adjustments.

Beyond its aesthetic beauty, this project embodies something larger. Crafting a fall wire tree centerpiece merges creativity with design thinking, transforming simple materials into a meaningful object through a process of iteration and visualization. As Susan Biali Haas reports in Psychology Today, research even shows that working with our hands strengthens spatial reasoning and fosters mindfulness (read more here). 

By the end of my workshop, the sun was dipping low behind the Berkshire hills, setting the horizon ablaze with pink and orange. The students packed up their tools, chatting about weekend plans, when they would see each other next, and ideas for future workshops I could hold. 

While real leaves will soon scatter and decay, the copper wire and fall-colored beads will continue to catch the light long after the snow begins to fall.

In spring 2025, the Williams College Makerspace partnered with the Stockbridge-Munsee Community to create truly meaningful engraved wooden appreciation gifts for museums that supported the repatriation of ancestors and sacred items. The gifts were presented at the Community’s reburial ceremony on April 24, 2025.

Each circular wood slice, roughly nine inches wide, is engraved with the Stockbridge-Munsee Tribal Seal and the words “Anushiik / Oneewe 2025”  meaning “thank you” in Munsee and Mohican. These tokens were designed to express gratitude, respect, and remembrance.

From Idea to Creation

Makerspace Program Manager, David Keiser-Clark, and Makerspace partner Divine Uwimana ’27 worked closely to bring the Community’s vision to life. Using existing wood slices from David’s collection, they carefully sanded and treated each one with natural oil to highlight the grain.

The engraving process balanced tradition and precision. The Tribal Seal, provided by the Community, was transferred into engraving software and etched using a laser or CNC machine. A small eyelet hook and twine were added to each piece so they could be easily displayed.

Challenges and Creative Solutions

Because each wood slice had natural variations in size and shape, the team adjusted engraving placements to keep the designs centered. Tight deadlines also meant careful scheduling from design approval in March to production and finishing in April.

The Final Pieces

The finished plaques feel both grounded and symbolic. The wood’s natural texture connects to the earth, while the engraved seal ties the pieces to heritage and identity. Together, they represent gratitude and shared stewardship between the Stockbridge-Munsee Community and museum partners.

Sustainability and Learning

This project emphasized sustainability, reusing wood, choosing natural oils, and minimizing waste. It also provided hands-on learning in digital design, engraving, and collaborative creation across cultural contexts.

A Gesture of Gratitude

The engraved wood appreciations are more than gifts; they are acts of respect. They honor the return of ancestors to their homeland and recognize the partnerships that made it possible, a reminder that craftsmanship can help carry forward stories of reconciliation, heritage, and care.

Special thanks to the Stockbridge-Munsee Community for their guidance and cultural leadership, and to the Williams College Makerspace and Science Shop for their support.

Folding Culture into Craft: 3D Pop-Up Cards at the FabLab

As part of International Education Week at Williams College, the FabLab hosted a 3D Pop-Up Gift Card Workshop, offering students a hands-on way to explore cultural expression through craft and design. Making pop-up cards is beginner-friendly and accessible, so the event welcomed participants of all skill levels. The focus? Create something personal: cards that reflected cultures, holidays, traditions, memories, or just artistic inspirations on paper.

The workshop setup was simple and inviting. Tables were covered in colorful pieces of paper, scissors, glue sticks, markers, and any materials for card making. Some students followed sample templates, while others sketched out their own ideas. There were Christmas trees and Diwali lamps, abstract patterns and handwritten poems. One student made a theater inspired card that showcased her favorite drama productions, while someone else made a card for a friend they missed back home. Another said, “This one’s for me, because self-love deserves representation.”

The process itself had its challenges and charm. Some folds took five tries. One student spent 15 minutes getting a single crease right, then yelled, “I DID IT!” loud enough to scare the glue sticks. Others discovered that lining up a pop-up platform just right takes a surprising amount of patience. But by the final hour, even the people who walked in saying “I’m not an art person” were holding up their cards like trophies.

And while it was all about creativity, the workshop naturally became a space for cultural exchange. As students worked, conversations unfolded about holidays celebrated differently across the world. Two students realized they celebrate the same holiday but with totally different traditions, and ended up swapping design ideas. Others shared music playlists or childhood stories while layering paper and ink.

Some cards were destined for family back home. Others were given to friends on campus, or tucked away as keepsakes. Whatever the purpose, each card became a small, folded expression of identity, memory, or experience. The FabLab provided the materials, but the room was filled with shared experience, laughter, and little victories.

In a fast-moving semester, this workshop reminded us to slow down and take the time to make something with our hands. It wasn’t just about making art; it was about creating space for connection, reflection, and a little fun. And when the last cards were folded and the scraps swept into the recycling bin, what remained was a room full of people who had built something: on paper and in a diverse community.

Stitch by Stitch: Building an Ocean in the Berkshires

Imagine walking into the ’62 Center for Theatre & Dance and finding yourself underwater surrounded by waves of vibrant coral, not in glass tanks, but crocheted by hundreds of hands across the Berkshires. This isn’t a fever dream. It’s the Berkshires Satellite Reef project, and it’s growing one loop at a time.

Worldwide Crochet Coral Reef

Worldwide Crochet Coral Reef

Williams College is diving headfirst into the worldwide Crochet Coral Reef project, a global, art-meets-science extravaganza designed by sisters Christine and Margaret Wertheim of the Institute for Figuring. This isn’t just art for the sake of beauty (though trust me, it’ll be stunning). This is art with a purpose, spotlighting climate change, celebrating mathematical forms, and building community all at once.

What’s a Satellite Reef, Anyway?

Participants working to craft the reef.

Glad you asked! The Berkshires Satellite Reef is our community’s personal contribution to this worldwide coral constellation. Over the next year, students, faculty, staff, and neighbors will come together to crochet corals of all shapes, sizes, and textures, using yarn, plastic bags, fabric scraps, and whatever else we can loop together.

In Spring 2026, these tiny textile ecosystems will unite as one immersive installation right here at Williams. Picture it: a fiber-optic reef you can wander through, crafted by hundreds of hands, from campus crochet circles to weekend workshops across Berkshire County.

Join one of our Coral Crochet Workshops and learn the basics, no experience required. You’ll get a free kit with yarn, a hook, and instructions (and maybe a super cute bag to hold it all). Or drop in for one of our Coral Crochet Circles and stitch alongside fellow reef-makers.

It’s low-pressure, high-reward. You’ll learn something new, meet great people, and contribute to something way bigger than yourself (literally, it’s life-size!). And your name will be in the credits for the installation.

Sustainable Stitches: Crafting with Care

53 pounds of yarn

All yarn was either donated or purchased as upcycled materials from the Old Stone Mill Zero Waste Maker Space

Here’s where it gets even cooler: this reef isn’t just about raising awareness, it’s about doing something. We’re experimenting with sourcing materials that are eco-friendly or upcycled (think yarn remnants, old plastic bags, strips of sheets, even industrial shrink wrap from commercial pallets). Our Makerspace and FabLab are testing out how to turn industrial shrink wrap, police caution tape, and packaging tape, and bulk sized cereal bags into crochet-ready materials. Who knew that caution tape and shrink wrap could become sea anemones?

Can You Use a Laser Cutter to Create Silk Screen Templates?

Ever wanted to reuse your old silkscreen without first having to clean off the old paint or emulsion? This innovative process explores reusing a stainless-steel screen by applying new acrylic paint to the screen to create a solid resist, and then, after the paint dries, removing sections of the resist with a laser engraver. This method has the potential to be a more efficient way of creating intricate and customizable screen printing designs, with substantially less prep work. 

Inspired by Carleton College’s Makerpedia, this method turns traditional screen printing on its head.

The result of using a laser cutter to burn acrylic paint off of a painted steel mesh screen. Instant "silk screen". Or is it?

The result of using a laser cutter to burn acrylic paint off of a painted steel mesh screen. Instant “silk screen”. Or is it?

Here’s Why this Rocks

  • Reuse it like a pro: Say goodbye to one-and-done screens. 
  • Freedom to create: Change designs as easily as switching out the acrylic paint resist. 
  • Laser precision: Get ultra-detailed results with modern tech. 
  • Perfect for small batches: Quick, easy, and ideal for mini-projects.

How to Make It? (The Fun Part)

I consulted with David Keiser-Clark, Makerspace Program Manager, and Jason Mativi, Senior Science Center Shop Engineer.

Step 1: Make The Frame

To make the project successful, I had to make a frame for the steel mesh. I learned how to use a metal chop saw in the Science Shop to cut the aluminum extrusions to the desired lengths. Before cutting the aluminum, I made sure to wear safety goggles and to clamp the stock down. I then carefully measured and cut a total of four pieces of aluminum.

I used the corner bracket cube to serve as a connector between the aluminum frame pieces, and screwed each side tight to prevent any wobble. 

Step 2: Attach the Screen

I then modified and customized Carleton College’s 3D screen lock. I added more thickness in the base of the screen lock and included holes on each end for the screws to pass through. Each hole has a diameter of 0.27 in.

I cut enough screen mesh to wrap over both ends of the frame. I then had to make two holes on each side of the screen and attached it as tight as possible to the extruded part of the frame. I added the screen lock, pressed, and secured it in place with a screw.

Step 3: Painting the Screen

I painted the mesh of the screen with a solid coat of acrylic paint. I found that painting one side of the screen is sufficient.

Step 4: Printing Process

I placed the screen on top of white drawing paper, with the screen facing the paper. Then, I made sure that it was secured so that it would not move as I applied fresh paint. I used around 10 ml of paint and painted it over the screen nice and slow to make sure that it didn’t bleed. I used the silicone squeegee to apply the paint evenly on the screen. Lastly, I slowly separated the screen from the paper. It was a little sticky, so I had to be careful not to smudge the paint. Sticky? Yes. Smudgy? No.

I may not have successfully created the perfect silkscreen. I think what I learned here is patience. Everyday I learn something new. It is not always about the goal. I was initially so focused about creating the perfect mesh screen, but I think the best part here was the process of figuring out how to make this work the way I wanted it to work. I learned that the beauty of creating something isn’t the result. It is every step you take, every turn of the screw, every laser that passes through, every stroke of the paint. It is those little pieces of an art that makes it a whole.

How Many Times Did I Fail? (A Love Letter to Iteration)

Spoiler alert

It wasn’t perfect the first time.
Or the second.
Or… well, you’ll see.

Unfortunately, we broke the auto-focus plunger (which we don’t use) on the laser engraver, because we set the height for the recessed screen and failed to account for the taller aluminum frame. Collision! (Sorry Mativi!!!) On the positive side, when the new part arrived, we learned how to repair the laser engraver.

Iteration #1: The first attempt of using the laser engraver to burn a precise design in the mesh screen, I set the power to 26% and the speed to 100%. I repeated this process three times to try and burn through the acrylic paint on the mesh. It didn’t work. The screen was still covered with acrylic paint on the other side of the screen. Epic fail. Paint didn’t budge.

Here’s what I learned: there’s no need to paint both sides of the mesh screen, as that only makes it more difficult to burn the paint off with the laser engraver.

Iteration #2: I next set the power to 100% and the speed to 100%. I again repeated this burn three times. It didn’t work. The screen was still covered with acrylic paint on the other side.

Bright side? The laser survived!

Iteration #3: Third time’s a charm, they say. I set power to 100% and the speed to 100%. It was basically the same as the second iteration, but this time instead of passing the laser engraver thrice, I passed it five times. The screen was still covered with acrylic paint on the other side but this time the acrylic was brittle and I was able to remove it using a razor blade and a steel brush. I gently took off all the brittle dried acrylic from the screen. The design survived. It worked! Oops! A new problem: applying fresh paint to the mesh screen results in paint bleeding out around the design borders. The print quality is terrible. There is still something missing. What’s next? I don’t know! Guess we will keep trying. 

A test for new solutions: Jason Mativi and Stephen Sabio experimenting with alternative methods after multiple laser engraving challenges.

Iteration #4: A recurring problem that I have identified is that the acrylic paint is challenging to burn away using the laser engraver. It’s time to try an alternative method. Mativi recommended that we try using the water jet to burn away the acrylic paint. So, I went to the Science Shop. And voilà, the water jet cut through both the acrylic paint and the mesh screen. The 30,000 psi water pressure and garnet dust was too strong for the screen material. We initially thought that might occur, but hey, at least we tried! 

Iteration #5: Back to the laser engraver. We tried experimenting around the speed and power of the laser engraver. There was no optimal speed and power to completely get rid of the acrylic. However, 100% power and 30% speed almost achieved our desired result. I still had to scrape a little bit of the acrylic off the screen. It was still worth the try!

Finally, it did work on iteration 5! Now, the big question: How many times did I fail? To be honest, I don’t know. I lost track along the way. The important thing is, I, we did it

When the backup fails ( water jet), it is time to go back to the original plan of the laser engraver and try again

After multiple attempts, there was success! Next came printing - an extremely careful process of separating the screen paper with little to no smudges.

Result? Fabulous

But more than just a crisp print, what I really took away from this process was growth. Every failed iteration, every broken tool, every “oops” moment pushed me to adapt, experiment, and stay curious. I didn’t just build a reusable mesh silkscreen—I built patience, problem-solving skills, and a deeper appreciation for the messy magic of making.

The learning process gave me hands-on experience with precision measurement, power tools, and mechanical assembly. I learned how to safely operate cutting equipment, interpret dimensions with accuracy, and ensure structural stability by aligning components tightly. It also sharpened my understanding of engineering tolerances; one loose screw, and the whole frame can wobble!

Beyond just assembly, this part of the process also introduced me to the practical side of design thinking, understanding how each material interacts under tension, and how even minor tweaks to the build can affect the outcome of the print. Turns out, there’s a bit of an art to building things that don’t fall apart under pressure. Literally.

Preserving History: How I used 3D scanning to preserve an ancient cuneiform tablet

I have always been someone who is interested in different languages. My passion sparked when me and my family moved to the United States from Venezuela, and I needed to learn English fast to help my family navigate this country, since they had less time to learn English than I did. Although I didn’t have an English tutor to formally teach me English, I taught myself most of my English through reading, which made me develop a love for languages in written form. Now, at Williams, I am a prospective Chinese Language major because I fell in love with the language after taking CHIN 101! So when I was given the opportunity to work on a project that was so related to my interest in languages, I jumped on it immediately.

Cuneiform is regarded as the earliest known writing system. These words are written into clay and then baked into a sturdy, but fragile tablet. I was also really surprised to learn that cuneiform was used to write several languages. I had the pleasure to work with When we got to work, I was filled with excitement, but also some anxiety about the unknowns. Anne Peale, a librarian that works closely with the college’s special collections. She taught me that this particular cuneiform tablet was (insert interview details here). She plans to use the 3D printed tablet for educational purposes, because the characters in the tablet are very legible and hold information about a person’s taxes. Not only would 3D printing the cuneiform tablet allow several iterations of it to be used outside of the special collections library, it also allows us to make the tablet bigger, which makes the writing a lot easier to read. I was really excited about all of this, and it honestly made me want to learn how to read this type of cuneiform!

When we got to work, I was honestly really nervous. I didn’t know what to expect. This project required a way to record the tablet’s intricate wedges and patterns in a way that makes the writing completely legible, so we decided to use the unfamiliar Creality scanner to 3D scan the cuneiform, digitizing it into a file form. In my opinion, the Creality software was really intuitive. It was fairly easy to connect it to the computer, and to figure out how to correctly configure the scan. The most challenging part of this project was figuring out how to scan the tablet in a way that fully recorded the writing. We had some challenges with this, as the most detailed scanning mode included stickers that told the scanner its location, and since we couldn’t place the stickers on the cuneiform, we had to place them in its perimeter, something that became really hard to deal with when we began to turn the scanner sideways to get the sides of the tablet, since it could no longer recognize the stickers due to the angle change. Another challenge we had was that the tablet was really hard to place in a balanced way that didn’t topple over, so we ended up putting a small weighted cushion to hold it up.

 

Since we couldn’t place the tablet in a way that was possible for us to capture all four sides in one scan, we had to do a scan for each of all four sides. Each side of the tablet took about twenty minutes to complete, and the Creality scanner is really heavy! Anne and I had to take turns scanning, and we were both so sore! Creality records 3D items by scanning each and every point on the item, and this tablet was so intricate that it had over a million points for each side! The more we scanned, the fewer points that were recorded, so we had to go around the item a lot slower and with a lot more complex angles to make sure we recorded every character.

After two hours, all sides were scanned. Now, the only thing that was left was to find a way to merge the different scans into the composite model of the tablet. Although the Creality software comes with a scan merging option, this did not work on our scans, so blender was used to merge it.

After a month, the 3D scanned cuneiform was ready! It was a lot bigger than the tablet, and a lot less fragile, and best of all, we now had a file that could be used for printing as many of these tablets as we want! I was really excited because it was also my first time getting to see a 3D scanned object up close, as well as hold it.

One side of the tablet is clearer than the other, so we are going to reprint the file as a resin print, because the material may help to raise the clarity of the 3D print. 

Working on this project was a true journey of growth for me. The complexity of 3D scanning and the delicate nature of the cuneiform tablet made every step a learning experience. There were moments when I felt challenged, uncertain about the technical aspects or the best way to handle the fragile tablet. But with each hurdle, I gained more confidence, honed my problem-solving skills, and improved my ability to think creatively under pressure. I have always been really interested in languages, and this project sparked an interest in the digital humanities and language preservation.The potential of 3D scanning in the field of digital humanities is endless. From preserving endangered artifacts to making them accessible to scholars and students around the globe, this technology ensures that history is no longer bound by geography or fragility. I couldn’t help but think, what other treasures could we preserve this way?

Well, not technically underwater. But when you walk through the main library entrance, you may find yourself surrounded by beautiful crocheted coral pieces. The Williams FabLab was hard at work on Wednesday, October 1st, crocheting hyperbolic corals to contribute to the Berkshire Satellite Reef Project.

The Berkshire Satellite Reef Project was inspired by the worldwide Crochet Coral Reef, a global community art initiative started in 2005 by Australian artists and sisters Christine and Margaret Wertheim. The initiative raises awareness about threats to coral reefs by bringing people together to create art. Here at Williams, participants were invited to the FabLab to learn how to make these pieces themselves. Led by Rae Bravo ’28 and Annie Trucano ’29, each participant received a kit with yarn, a crochet hook, and a hip homemade bag to carry it all in.

Each crochet piece is made with upcycled yarn from community donations. The creations have unique shapes and colors, reflecting the vibrant biodiversity of reefs, which are under threat due to changing ocean conditions from climate change.

FabLab and Makerspace Make Plastic Yarn from Industrial Shrink-wrap

The FabLab and Makerspace collaborated to purchase a functional replica of a Meyer rope making jig. (Martin Meyer of Sheffield, IA, received patent 1,510,691 on October 7, 1924, for a 4-strand hook, non-geared rope machine.) 

We tested our Meyer prototype during the June 2025 Alumni Weekend, where many kids (and adults) had opportunities to cut 18″ wide industrial shrink-wrap into manageable one-inch widths, and loop them onto this hand-crank machine, and crank, crank, crank! Their work caused the four separate plastic loops to twist, until finally the four loops would twine together, creating a reasonably strong braided plastic yarn. We donated this plastic yard (“plarn”) to the Berkshire Coral Reef Project, where people subsequently crocheted it into the hyperbolic coral reefs that will be on exhibition.

Studying Savannah Sparrows on Kent Island

The Williams lab studies Savannah sparrows (Passerculus sandwichensis), small migratory songbirds that live in grassy fields across North America (Cornell Lab). Savannah sparrows have been the subject of a long term study at Bowdoin College’s field research station on Kent Island in New Brunswick, Canada.

Savannah sparrows have been recorded on Kent Island since the 1960s and their songs have been recorded intensively since 1980 (Williams et al., 2018). Clara Dixon, who thoroughly recorded songs in 1980 and 1982, inspired a continued in-depth study of Savannah sparrows to this day because their songs are an excellent model for studying cultural evolution, the socially learned traits of populations change, and the bird song learning has parallels with the development of human speech (Williams et al., 2022). Male Savannah sparrows learn components of their songs from various tutors, including their biological father, social father, and both hatching and breeding-year neighbors. They then use these songs to attract mates and defend their territories.

Professor Heather Williams first went to Kent Island in 1973, her first year of college. She has maintained her connection to the island, and realized the potential to contribute to the Savannah sparrow research by studying a local population in Williamstown since 2005. Birds are systematically color-banded—given a unique three band color combination on their legs so that they can be identified with binoculars—and their songs are recorded. In addition to analyzing songs, observing birds’ responses to variations in note count and spacing in songs is valuable for understanding which factors drive changes in song traits over time. To study birds’ reactions, our lab conducts playback experiments, which entail placing a speaker in the middle of a bird’s territory, playing stimuli of songs with either variable note spacing or note type, and recording a bird’s response.

Birds may sing an additional ‘chuck’ note in either an earlier or later interval, variable spacing between x notes, and other soft notes that fall between the introductory notes. Last summer, we investigated what drives the changes in the occurrence and number of chuck notes in songs, and how the spacing of x and other notes may influence a bird’s reproductive success.

Birds typically seek out the source of the song in a playback study. Placing a fake bird near a hidden speaker can enhance a playback because the bird directs its behavior towards the specific target. Taxidermy Savannah sparrows have been used in such experiments, but as Professor Williams warned us throughout the summer, they do not last long. The real birds aggressively attack and eventually destroy that type of model. 

We asked the Makerspace to 3D print a durable bird that we could repeatedly use in these playback experiments. The students brought a free 3D model of a Song Sparrow to Alice Sore ’27, a Makerspace student worker, since it was similar in appearance to the Savannah Sparrows we study. Using Blender, Alice modified the model by removing the legs, which would have been too fragile to print and nearly impossible for the bird to balance on. She replaced them with a simple base that could be hidden among leaves or grass in the field. After an initial failed print, Alice successfully produced two near-perfect models, which were then handed over to our lab for painting. A member of our lab, Hannah Cumming ’28, who is a prospective Biology and Studio Art double major, painted the models to match a Savannah Sparrow’s typical plumage. A member of our lab, Hannah Cumming, who is a prospective Biology and Studio Art double major, then painted the model to match a Savannah sparrow’s typical plumage. We gave our two painted models an imaginary three-band color combination as their name, choosing B.OG (Black band on the left leg, Orange band over Green band on the right) for one, and GO.B (Green band over Orange band on the left leg, Black band on the right) for the other. The names were inspired by the amazing peatland environments on Kent Island.

B.OG, like some of his living and wild counterparts, migrated to Canada with our lab this summer to spend time on Kent Island. We used the model bird in playback experiments to test female responses to song variations. We placed B.OG in the mown path in the middle of a territory and hid the speaker nearby in taller grass. We then conducted the playback experiment to see whether females would respond aggressively to the songs or with intrigue. Approaches without aggression by a female would indicate that certain song traits are “sexier,” meaning the trait improves a male’s reproductive fitness. An aggressive approach would indicate that female choice is not driving changes in this song trait.

Due to the timing of our experiment, females were feeding their nestlings and did not respond to the songs or birds. Due to the timing of our experiment, when females were actively feeding their nestlings, they did not respond to the songs or birds. This highlighted for us the importance of seasonal timing in behavioral experiments.

We later used GO.B to test male responses in Williamstown. We placed the 3D printed model on a stake in the meadow and played songs to stimulate birds’ responses. Subjects flew around the model and treated it the same as live birds also sitting on posts: the subject approached the bird (whether live or 3D printed), and when it did not fly away, the subject returned to its original post.

This project also taught us how interdisciplinary collaboration between biology and technology can open up new methods for fieldwork. Our lab is excited to continue using the model birds in future research projects! In the future, we hope to expand the use of these models to test additional song traits and to explore how responses vary across seasons and populations.

3D Printed Topographical Maps of Louisiana, Bhutan, and the Berkshires!

Arriving in the Berkshires

I arrived at Williams as a freshman never having visited the campus. Despite the admissions webpage’s best efforts to warn me, I was still shocked by the beauty of the mountains. Various trips to Pittsfield and Albany, mountain day hikes, and other excursions took me outside the main campus, but I couldn’t keep track of all the mountains, and I had little to no sense of the Berkshire geography. I put off looking closely at a map to orient myself because I kept thinking this would all be so much easier if I could just run my fingers over a topographical map of the area.

Creating Meaningful Gifts

Last semester, I decided that a 3D printed map of Williams would make a nice gift for my friends who were graduating. And, with the help of the website https://touchterrain.geol.iastate.edu/ and David Keiser-Clark at the makerspace, I made it happen. It was actually pretty easy. Touchterrain let me trace out the area I wanted a map of and download the elevation data as an STL file, which I sent to David, who got it printed.

The Process

When I first came to the Makerspace with an STL file of the Williams College campus, my goal was simple: create something meaningful for my graduating friends. I wanted to give them a small, lasting reminder of the place where we had spent the past four years. That idea soon grew into a larger project, with maps of Williamstown for several friends and a special map of coastal Louisiana for someone whose thesis focused on flooding in that region.

In addition to maps of Williamstown, we printed Paro, Bhutan for one of my friends who had studied abroad there and part of the Louisiana coastline (with the height scale exaggerated 500 times) for another friend who did his thesis on natural-technological disasters in that area and relied heavily on elevation maps.

The only map I kept for myself was a map of Amman, Jordan, where I studied abroad during my gap year. I returned there this summer thanks to funding from Williams’ Wohabe Fellowship, and one of the best parts of my trip was using my map to better understand the geography. By the end of my weeks there, I had a really solid grasp of the layout of the western side of the city and could place my memories from mysemester there in my mental understanding of the area.  

I’m really grateful to the Makerspace and David for helping me print these maps, and for anyone interested in 3D printing topographic maps at Williams, I’d recommend multi-colored filament so that the layers of the map change color with height and I’d warn that when painting a white print, some of the paint can find its way inside the plastic and get stuck there. (Also, for anyone looking for a good, online topographic map, I recently found the website https://en-gb.topographic-map.com/, which overlays color-coded elevation data onto Google Maps).

At the Makerspace, I experimented with materials and techniques. I tried different filament colors to see which would make the contours stand out best. For the Louisiana print, by exaggerating the elevation by 500 times, I brought out subtle topographical changes that are normally almost invisible. This choice created a striking visual effect and started conversations about how we interpret geographic data and how exaggeration can be used to reveal patterns that might otherwise go unnoticed.

Final Reflection

The final prints are more than just maps. They are pieces of memory, friendship, and curiosity. They invite touch and exploration. For me, they represent a way to connect academic learning, travel experiences, and personal relationships. For the friends who received them, they are a reminder of place and community at a moment of transition.

Environmentally Sustainable 3D Printer Upgrades Reduces E-Waste

Alice Sore '27 upgraded our 3D printers in an environmentally sustainable manner by replacing specific componentry on our older models. This was both cost-efficient and eliminated disposing them as electronic waste (e-waste). CNBC projects that global e-waste is projected to reach 82 million metric tons by 2030.

Alice Sore ’27 upgraded our 3D printers in an environmentally sustainable manner by replacing specific componentry on our older models. This was both cost-efficient and eliminated disposing them as electronic waste (e-waste). CNBC projects that global e-waste is projected to reach 82 million metric tons by 2030.

Out of everything we use here at the Makerspace, our 3D printer fleet is the MVP. Students and faculty rely on these machines constantly, cranking out everything from quick concept models to full-blown research prototypes. So when we had the chance to upgrade our entire fleet to the Prusa MK4S, we jumped on it. First, we sustainably upgraded our two older MK3S printers by swapping out componentry, resulting in like-new printers without causing the typical e-waste so ubiquitous to technology. Unfortunately, our aged Dremel 3D45 printers were built as single-use machines, (without options for forward compatibility) and so we had to dispose of those (after removing potentially useful parts) as e-waste. We use Prusa 3D printers because they are reliable AND because the Prusa ecosystem (company and community) encourages environmentally sustainable upgrades and modifications.

Spoiler: totally worth the effort.

Environmentally Sustainable 3D Printer Upgrades Reduces E-Waste

Alice's 3D printer upgrades mean much faster print speeds and they make nozzle swaps incredibly simple.

Alice’s 3D printer upgrades mean much faster print speeds and they make nozzle swaps incredibly simple.

Let’s be real. The MK4S upgrade isn’t just a tune-up. We basically gave our printers a heart transplant. Actually, several transplants. Almost every single part got swapped out except the frame and power supply. When you use these printers now, you’re running on next-gen hardware.

So what changed? Let’s break it down.

The Nextruder is a game changer. Think of it like switching from a clunky flip phone to a smartphone: faster, smoother, and way easier to customize. This new extruder (which we already love on our Prusa XL) cranks up print speeds and makes nozzle swaps incredibly simple. Like swapping AirPods simply.

No more manual bed leveling. The load cell handles it automatically, using the printer’s nozzle to probe the bed. Set it and forget it.

Hello, 32-bit mainboard. This brain upgrade unlocks fancy software features like Input Shaping and Pressure Advance, which translate to higher quality prints with cleaner layers and fewer weird artifacts. Plus, native support for Prusa Connect means Wi-Fi everything. Less standing around waiting, more grabbing coffee while your print starts itself.

Installing the Upgrades

Each upgrade took about eight hours. That’s a whole day of taking the printer apart screw by screw, then putting it back together like a giant LEGO set with instructions that actually make sense. Prusa nailed the documentation. Every step was clear, every part was labeled (even the screws!), and honestly? It was kind of satisfying when each printer roared back to life on the first test print.

Lights, Camera, Printing!

We also had to get creative with our camera setup. The old method of connecting a Raspberry Pi Zero directly to the MK3S doesn’t work with the MK4S hardware. No problem. We kept the same gear and just reimagined how to use it.

Here’s the setup now: each MK4S has a custom 3D printed arm with a ball joint socket. We mount a case containing a Raspberry Pi Zero W and a Raspberry Pi Camera Module 3 NoIR right there. Each Pi runs Raspberry Pi OS Lite, connects to our network over Wi-Fi, and fires off a new still image to Prusa’s servers every 10 seconds. You can check in on your print anytime without walking over.

Down the road, we’re planning to upgrade the code when Prusa Connect adds support for live video feeds. Because who doesn’t want to watch their print in real time?

What This Means for You

So what does all this nerdy tinkering actually mean for you?

  • Shorter wait times. Prints finish almost twice as fast.
  • Cleaner results. Better hardware and smarter software mean fewer layer lines, better first layers, and more consistent quality.
  • Fewer heartbreaks. You know that sad moment when you come back and your overnight print has turned into spaghetti? Yeah, way less of that now.
  • Remote monitoring. Check your print from your phone. Anywhere. Anytime.

Faster Prints, Fewer Headaches: our 3D printing services just leveled up. Whether you’re prototyping a new design or printing something for research, these upgrades make the whole process faster, smoother, and a whole lot less frustrating.

Come by and see them in action!

Revving Up STEM Education: Optimizing Mousetrap Cars for the Makerspace STEM Kits

Imagine a classroom of 5th graders buzzing with excitement as their mousetrap-powered cars zoom across the floor, each tweaking their design to outrace the others – all while learning the physics of potential and kinetic energy. That’s the vision behind the Williams College Makerspace’s Sustainable STEM Learning Kits project, and this semester, I had the chance to dive in, redesign a car from scratch, and use statistical methods to optimize its performance. Spoiler: it involved a paintbrush, some copper wire, and a magazine holder: improvisation at its finest!

Background: Building on a Legacy of Learning

This project builds on the groundwork laid by the Makerspace, Williams College CLiA, and the Zilkha Center through the TIDE Grant initiative, which aimed to create sustainable, reusable STEM kits for under-resourced 5th and 6th grade classrooms. As detailed in this Makerspace blog, one of the main ideas for the stem kits is a model car assembled from sustainable, reusable materials with some 3D-printed printed parts to teach energy concepts, aligning with Next Generation Science Standards (NGSS). Previous Makerspace student workers Divine Uwimana ’27 and Alice Sore ’27 created an initial design that used a rubber band to power the car. My work involved building up on and enhancing this initial design and exploring other forms of potential energy that could be used to power the car.

My Journey: From Brainstorming to Rapid Prototyping

I kicked things off by meeting with Divine Uwimana to understand the project’s history and progress. Then, I teamed up with Izzie Tarantino for this joint endeavor, guided by Makerspace Program Manager David Keiser-Clark. We brainstormed energy sources for the car: elastic bands, flywheels, mousetraps, and motors. Izzie focused on elastic energy (expanding on the previous work by Divine and Alice) and modular designs, while I explored flywheels and mousetraps. I initially designed a flywheel with 8 ball bearings but decided to pivot to the mousetrap car for this semester, leveraging the existing car body as a starting point.

Having dabbled in Fusion 360 during a previous photogrammetry project, I saw this as a chance to deepen my skills. I tried modifying the prior design, but missing sketches made it tricky, so I started from scratch. The learning curve was steep; I relearned Fusion 360 mirroring and shape patterns, tackled advanced concepts like threading an axle, and spent hours troubleshooting. After printing the car body, I turned to rapid prototyping to test ideas without wasting resources. For instance, I used a paintbrush as a pole to connect the mousetrap to the axle with a string. I also experimented with connecting two mouse traps in series, designing a scalable system where one trap triggers the next. To test this trigger mechanism, I improvised with cardboard and copper wire, containing the setup in a magazine holder – Makerspace creativity at its best!

Merging Design with Data: A Statistical Experiment

The project took an exciting turn when I realized it aligned perfectly with my Statistical Design of Experiments course (Stats 344). On one hand, I had an extracurricular project that was inherently experimental; on the other, I was learning statistical methods eager for application – a textbook case of supply meeting demand with zero opportunity cost! My Stats 344 team, consisting of Lee Mabhena ’25, Victor Cazabal ’25, and myself (26’), met at the Makerspace to run a 2^(7-4) fractional factorial experiment, testing seven factors: floor type (carpet vs. hard floor), wheel friction (high vs. low), string material (polyester vs. rubber band), number of mousetraps (one vs. two), pole length (short vs. long), car length (short vs. long), and added weight (0 g vs. 100 g). Our goal? Finding the combination that maximizes travel distance while identifying which factors matter most, enabling kids to experiment with configurations and compete.

After multiple experiments, including a central composite design, we pinpointed an optimal setup: 16.37 g weight and an 8.56-inch pole length, predicting a distance of 381.27 inches. Confirmatory runs (389.14, 380.88, and 350.55 inches) validated our model, and we confirmed that floor type, weight, number of mousetraps, and pole length significantly impact performance, while wheel friction, string material, and car length had less effect.

Reflections and Next Steps

This project was a game-changer for me. I sharpened my Fusion 360 skills, learned the value of rapid prototyping, and enjoyed my first Makerspace team collaboration with Izzie –our brainstorming sessions were a highlight! Looking ahead, I’d love to revisit the flywheel design as an energy source and eventually create a universal car body that supports multiple energy sources, like a “universal adapter” for elastic, flywheel, or mousetrap power. This would give students even more ways to explore physics while fostering creativity and competition. For now, I’m thrilled to have contributed to a project that empowers young learners and bridges classroom learning with hands-on innovation, helping students see science not as abstract equations, but as something they can build, test, and improve.

Hyperbolic Paraboloid: The Ball that Wouldn’t Roll Away

At first glance, the shape looks like a saddle, a sweeping hyperbolic paraboloid with a ball resting right at its unstable center. Under normal conditions, gravity would quickly win, sending the ball rolling away. But the magic begins when the surface rotates. Suddenly, what was once unstable becomes stable: the ball lingers at the top, as though defying gravity. This simple but mesmerizing demonstration is more than a parlor trick. It’s a tangible, mechanical analogy for a Paul Trap, a device used in quantum mechanics experiments to confine ions and electrons with oscillating electric fields.

The idea to bring this demonstration to Williams College originated in conversations with Professor Fred Strauch, who saw its potential for enriching the department’s Quantum Mechanics (PY301) course. Project owner Brough Morris, Instructional Support Specialist for Physics and Astronomy, and Makerspace student worker Alice Sore ‘27 took on the task of designing a version that could withstand repeated classroom use. Their challenge was to improve on an earlier fiberglass prototype, which only managed to keep the ball stable for about five seconds before imperfections in the surface or misalignment caused it to fail.

This photo displays the hyperbolic paraboloid (connected to a base with rotational motor) that the Makerspace 3D printed. Unlike fiberglass models, this included smooth curves and precise geometry and no bumps. The Makerspace has the largest 3D-printer beds on campus.

A 3D-printed model offered a promising solution. Unlike fiberglass, which introduced bumps and inconsistencies, 3D printing could produce smoother curves and more precise geometry. Brough designed the surface to be as wide as possible while still fitting in the Makerspace printer’s build area, which was larger than any other printer available on campus. Multiple design iterations in CAD ensured that the final geometry struck the right balance, shallow enough to reduce instability, but still faithful to the physics of a Paul Trap. Rigidity was also essential: any flexing or vibration in the surface during rotation would send the ball off course. To get the balance right, Brough consulted with Jason Mativi, Senior Science Center Shop Engineer, about print density and material strength, ensuring the final model would be both stable and durable.

The fabrication process involved careful modeling of the hyperbolic paraboloid in CAD. Once the paraboloid was printed and mounted on a rotating base, the demonstration came to life. Smooth, precise, and stable, the 3D-printed saddle surpassed the earlier fiberglass attempt, holding the ball far longer (see video) and illustrating the physics concept in a way that is both intuitive and unforgettable.

A critical addition to this setup is the custom control box that Brough and Kevin Forkey, Lab Supervisor and Lecturer in Physics, built to regulate the motor speed. The experiment only works in a narrow frequency range, around 100 rpm. A little too fast or too slow and the ball will slowly drift away from the center before eventually flying off. At the correct speed, though, the ball doesn’t just sit precariously balanced, it truly stabilizes. If nudged slightly, it self-corrects and returns to the center. This visual proof of a dynamically stable equilibrium makes the analogy to the Paul Trap even more compelling.

The project draws inspiration from a similar setup at Harvard, but with a Williams Makerspace twist. The collaboration between Brough and Alice highlights how a mix of creativity, technical skill, and persistence can transform abstract concepts into hands-on learning tools. By June 2025, the hyperbolic paraboloid demonstration will be ready for classroom use, giving physics students a chance to see, not just imagine, how stability can emerge from instability. With the wires cleaned up and the motor properly mounted, the demonstration is now classroom-ready and will be used in Quantum Mechanics (PY301) starting June 2025.

What makes this project exciting is not only the final product but what it represents, the blending of mathematical surfaces, modern fabrication techniques, and physics pedagogy. In the classroom, the spinning saddle offers more than a visual spectacle. It anchors a difficult idea: the dynamic stabilization of particles in a Paul Trap in an experience that students can watch unfold before their eyes. It’s proof that sometimes, the best way to teach quantum mechanics is to let a ball roll across a 3D-printed saddle and show that, with the right motion, even instability can be tamed.

Does Optogenetic Inactivation of TRPA1-expressing Neurons Diminish Heat Avoidance in Drosophila Larvae?

Authors: Claire Colvin ’27, Tess Everett ’27, Shiv Patel ’27. 

For our Neuroethology class (NSCI 324/BIOL 314) with Professor Charlotte Barkan, we decided to explore the extent to which TRPA1, an ion channel expressed by heat-sensing neurons, is involved in heat sensation. We wished to use optogenetics to investigate how the inactivation of cells expressing this channel influenced heat avoidance behaviors in Drosophila larvae. In order to inactivate the channel under blue light, we crossed two fly lines (UAS-ACR2 and GAL4-TRPA1) and used their resulting progeny.

To observe heat avoidance in ambient versus blue light, we wanted to create a model that could maintain a heat gradient with a cold and hot side of the arena (a Petri–dish). This led us to partner with the Makerspace to bring this experimental design to life. We helped design and then Makerspace student worker Izzie Tarantino ‘28 modeled and 3D printed a dual-chamber water bath that allowed us to cool and heat each side individually. The arena was partially submerged within the model, allowing for the creation of a temperature gradient to observe larval behavior. Heat avoidance behavior was quantified by recording the number of larvae present on each side of the arena at 30–second intervals over 5 minutes. We hypothesized that the inactivation of TRPA1 (blue light condition) would disrupt heat detection, manifesting as reduced heat avoidance of the hot side of the arena. 

Early data acquisition: small change in temperature

Early data acquisition: small change in temperature

During our data collection, we learned that the temperature of the water did not exactly reflect the temperature of the arena. This was due to the material within the Petri-dish, called agar. While this substance is crucial because it facilitates larval movement, agar is not particularly conductive to heat. The cold side of the arena was warmer than the surrounding cold water beneath it, and the hot side of the arena was cooler than the surrounding hot water. This led us to adjust our methods. First, we opted for more extreme water temperatures within each chamber to achieve a true temperature gradient. We also decided to use an infrared thermometer to ensure we knew the exact temperature experienced by the larvae on the surface of the arena, instead of using the temperatures of the water below as a proxy. With these adjustments, we gathered much better data. 

Later data acquisition: larger change in temperature

Later data acquisition: larger change in temperature

Our preliminary results showed that the inactivation of TRPA1 partially leads to the reduction of heat avoidance behaviors, following our hypothesis that TRPA1 is involved in heat sensation, but demonstrating that TRPA1 is not the only ion channel involved in temperature detection. We would like to note that due to the few trials performed, these results are not statistically significant, and more experiments are required to confirm the viability of our findings.
