My new plan for the keycap was a single piece with rounded edges to be comfortable and look clean. Most of the old code went away, but now I had a solid plan of what I wanted to make.

This tip popped up in my YouTube feed, and I was a little bored, so I watched. The artist was ripe with dry humor, and I tried to honor that in my article.
My prints were comfortable, but they had a couple of problems. The first problem was functional. The bases were so long that the keyswitches couldn't activate, so I fixed that. The second issue was a case of printer settings. I made all my plungers solid, which was more expensive, but they were heavier than I wanted for a hand-mounted keyboard, so set them to a low percentage infill.
Plungers on my hand
I made a knob in OpenSCAD. The encoder had a flatted shaft which wasn't compatible with my potentiometer knobs. It was a fun diversion to make my own, and I should have use of it in the future.
Knob render
I made some small model changes and printed new parts, but the biggest step I took was to start soldering components together. I stopped when it was clear that I should create an IO list before committing any wires to microcontroller pins.
Soldered parts
I made my IO list, but it wasn't a fast process. Many ATMEGA Arduino boards can assign any pin as an input or output, but this board had restrictions on which pins could act as outputs. Most points were out of order, so for the four keyswitches, I picked the only sequential four.
