Makerspace Presentation 2022

Learn about the cool stuff that students and faculty have been making in our academic makerspace in our summer coffeehouse presentation! Our makerspace is located in the library of a small liberal arts campus and serves all academic departments.

Reducing Waste in a Makerspace

To remind students to think sustainably while thinking creatively, we created this sign for the space.

Text reads:


  • Take care of materials and supplies to reduce waste.
  • This means putting filament in bags with ends secured to reduce filament spoilage and tangles, which leads to bad prints.
  • Put supplies back where you found them. This prevents loss, duplicates, and keeps things from getting broken.
  • Use just what you need. Mistakes and drafts are an important part of the making process, but be mindful.
  • Measure twice when needed and double-check machines, materials, and your project before starting.


  • Use scraps when possible- we have fabric, wood, acrylic, and more scraps around the space for your creative inspiration.
  • Failed 3D print? Try to find a new use for it! If you can’t but you think someone else could, put it in the failed prints box.
  • Use the sewing machines to mend or upcycle your clothes or thrifted clothes.
  • Use the other materials in the space to fix your broken items.


  • Place recyclable materials in the marked recycling bin in the makerspace. This includes paper, cardboard, and plastic (rinsed out, if necessary).
  • Plastic bags and other plastic film as well as batteries can be recycled in the library entryway.

3D Printing and Ecology: Utilizing Additive Manufacturing to Save a Federally-threatened Native Plant Species

The Evil Weevil

By Harsimran Kalsi

     Previously, I collaborated with Prof. Alyssa Hakes of the Biology department on a very interesting project, which highlights 3D printing’s high versatility and interdisciplinary potential. We worked on a project which may allow us to protect an endangered plant species known as the Pitcher’s Thistle (Cirsium pitcheri). This unique intersection of ecology and 3D printing is not intuitive at first, but it’s also an intersection that has only recently been explored by the scientific community.

     Prof. Hakes has a wonderful page on ( which describes the project in depth. In short summary, the goal was to fabricate decoys of the Pitcher’s Thistle (PT) to attract weevils away from the real and vulnerable plant. We wanted to make the decoys as high fidelity as possible considering things like shape, size, color, and reflectiveness. We also wanted to optimize these decoys such that they were easy to print/work with and easy to deploy in the field.

     During the initial design phase, one of the biggest challenges was trying to replicate the topology of the PT. The small pineapple-like protrusions on the curved surface of the bud, proved difficult to design and we anticipated that it might also be challenging to print. In a stroke of genius, Angela Vanden Elzen had the creative idea to modify a design she’d happened to come across on Thingiverse. The file was of a lamp shade which Angela then further modified by placing two inside one another, adding a sphere to the middle, and inserting a hole through the base (so the decoy could be placed onto a dowel which would act as the plant stem). This ultimately resulted in a decoy which looked something like this:

     Interestingly, we discovered that the “spiky” parts of this design weren’t printed exactly like they are shown in the .stl file. Instead, because of printing limitations (e.g. the angles of these edges) we ended up with decoys that displayed intricate, thin, somewhat “frilly”, and lengthwise fibers which surrounded the bud. Ultimately, these fibers actually helped make the decoys even more realistic in terms of texture. They also facilitated some of our feasibility constraints (e.g. no supports in the design makes it quick to scale up printing and the protrusions may make adding/maintaining adhesive easier).

     As we were printing, we utilized several different shades of green (including an algal based filament which was surprisingly . . . aromatic). We initially relied on prof. Hakes’ previous field experience to determine colors that best match the PT. Later we decided we could use images of the PT (taken by prof. Hakes in the field) to obtain a hex code and subsequently a customized color filament. But where could we order customized color filament? As it turns out, about 10 minutes away from the Makerspace is a local business called Coex, which supplies several different types of filament. We then began collaborating with them to create this custom filament.

A few prototypes printed with different filaments.

            Finally, we began printing the fourth (or so) iteration of the decay using the custom filament from Coex. We batch printed several for prof. Hakes to use for field experiments over the summer. For more updates about the project, check out this link:

Making sound with film

By Kelvin Maestre

Laser cut film

This winter, I took a course in Artisanal Animation. For my final, I was tasked with making an animation using any of the mediums we had studied. I was personally drawn to direct on film animation. It wasn’t the images that I was after, but the sound. The biggest inspiration for the project was Norman McLaren. McLaren was an animator for the national film board of Canada. He specialized in direct on film animation. One of his most impressive feats in the medium was being able to create his own hand drawn sound. I had made previous attempts to emulate McLaren’s process with little success. This time around, I decided I wanted to tackle the project in my own way. My initial thought was to use the laser cutter in the Makerspace, but the test ended in nothing but burnt film.

I had to consider another option. The only other machine I could use was the silhouette cameo. I was hesitant at first because I had never extensively used the machine. To my surprise, it was very easy to use making my overall process faster. Now I had the tools to etch the film, now it was time for the sound.

Sadly you can not just plop and audio file in the Silhouette cameo’s software. The cameo works best with vector based graphics, so get our sound to be cut-able we need to make it into an image file first. A quick Google search for “Sound to waveform graphic” yielded a website that does just that (link will be below). Once I had a image of my sound file, I ported it into the cameo’s software, resized the audio image, lined it up, and hit send.

I wanted to see how far I could push the technology, and so I tried to etch a stop motion animation I made of my hand. The animation was shot in black in white (easier for the software to recognize), each image was then combined into rows of 24, plopped into the cameo software, and cut. The results was imagery that didn’t reflect the source it came from. The machine had added a layer of abstraction (you can see the result at the end!)

Here is a link to a video of the film being run through a projector!

Below is a list of links I used to do this project, including a link to an in-depth guide on how to do this yourself:
