My neighbor has an aquarium that just seems intent on sharing its watery insides with his floor. They already had to replace the floor once because of it, and just the other day, it failed again. Had no one been home, it would have cost them their new floor!!
The problem was the clips that hold a piece of glass over the top. They were too short and the glass can fall inside, messing up the pump.
So, they asked if I could make a replacement. Here’s one of the four clips:
That lip in the is just a little too short. Since I only have PLA handy right now, I want to make sure it could hold the (about one pound, I’d later find out) piece of glass. So, I over engineered it:
I first took measurements with calipers, drew out the current one, and came up with some options to prototype:
This was a very simple design, so I made two versions in Tinkercad. It's a free website where anyone can create all sorts of simple models.
I made this design simply by making a larger box, adding two 'hole' boxes and then grouping them together.
Before grouping
I took the models into a beta version of Cura to slice them. The beta version is designed to make stronger pieces by adjusting the infill thickness (I used Chep's 4.12 setting profiles)
Here’s the results. They are a lot thicker than the original, by design!
I took the smaller of the two and decided to stress test it:
Hard to see, just above the welded metal.
I was ready to run at any moment!
25+ pounds had no effect for about three minutes. The last photo is a 50 pound solid piece of metal that I’ve used as a makeshift anvil! I tested for about a minute. I would have gone longer, but I needed to help balance it, and I wasn’t wearing steel toed boots!
While these pieces won’t be submerged in water, I decided to coat them with acrylic anyway to help keep moisture out. I plan on making PETG replacements soon, and this material is stronger and handles water and UV better, but wanted them to have something they could use now.
Includes some motion capture work (including the first team to integrate mocap into their 48 hour game jam!), videos that I produced and edited, and oh yeah, wearable LED experiments.
In 2020, our kitchen suffered water damage and required a complete
cabinet replacement. I came up with a unique backsplash pattern. No contractor
would take this job on due to its complexity, so I decided to do it myself.
After extensive material tests and
photoshop compositions we arrived at these two tiles. Because we had under cabinet
LEDS, some worked better than others. This composite image was what sold me on these tiles and the more complicated design idea:
Laying down the hex tiles was fairly easy in retrospect. Getting
the rectangle tiles cut to size was a bit of a challenge. To speed up the
process, I made tracings of the gaps in the hex tiles, and noted where the
lines needed to go:
This was the combo that made the magic: Translucent grout and Technoglow Ultra Glow Blue.
The final results (only a fade is photoshopped, no other manipulation done to images) Over a year later, and I’m still happy when I see this at night:
AdaFruit Electronics Design & Scripting, 3D Design & Printing, Sewing:
This project is something I've wanted to do for a long time, and finally had a compelling reason to do it. I mean, who doesn't want glowing 3D printed barnacles on the back of their jacket?!?
Here's my (abbreviated) process: I measured that panel of my jacket:
I sewed a piece of denim that would fit that spot. I modified my original idea to include room for a pocket to hold the battery (upper right). Clasps were sewn onto it and the jacket
I 3D printed a housing for a Gemma M0, and attached that to the jacket:
I designed the barnacles in Maya, exported to Cura and made a few iterations to best work with the jacket
Once it was all together, I scripted different patterns for the design:
Final result (see above for video!)
3D Printing:
In addition to the above jacket attachment and three PPE mask sewing templates I designed and shared on Thingiverse, I also have also designed snowflakes, and helped a friend replace a lost chess piece.
Snowflakes
This snowflake was designed in Illustrator, but because it had a more complicated grouping than other designs I've made, it wasn't working well in Tinkercad. Some of the holes were still filled in, no matter what settings I changed. So, I took the SVG from Illustrator into Blender, and extruded the shape there, exported an STL, and then sliced it in Cura.
The takeaway is to not be tied to any given pipeline when designing something.
Custom Snowflakes I made for family
Chess Pawn
A close friend of mine knew I had a 3D printer, and wanted to replace a missing chess piece from a set he got in Mexico. He presumed I also had a way to 3D scan items. I figured out how to do it with my iPhone 7, and a free version of 3DF Zephyr Free. After taking 30 photos of the piece outdoors on a cloudy day, I was able to get it to successfully reconstruct! Not bad for a shiny object. I took it into maya to clean it up a little, and to make a solid base. From there, I exported an STL and brought into Cura for slicing.

Miniature painting techniques paid off!
And, here is is reunited with the rest of the set:
Sets, Props, and Motion
Capture:
Taken from my time at Bungie, this showcases my ability to solve all sorts of
problems by making props and set pieces, usually with limited time and resources: 2019 Troy McFarland Mocap Demo Reel
Pictured: the incredible mocap actor, Richard Sloniker!
Art From Scratch:
I tried to make a painting completely from scratch! I made several pigments and
met Theodore Gray in the process, but have yet to complete this project. Something to hop back on at some point: Troy

Copper + vinegar = (toxic) blue/green crystals!

Music:
After learning the basics of Ableton Live, I challenged myself to make an album in one week. I hesitate to post this, as it seems like everyone has an album these days. But, I'm very excited to continue to dive into Ableton. In conjunction with Max for Live, I would have the ability to make some very interesting installation pieces that can take real time data/input to affect compositions and even lighting! 1
