Fixed small measurement errors, realigned the components, and worked on the cover piece. While I was working on the cover piece, I noticed a small piece sticking out, a sign of a slightly mismatched measurement. It turns out that most of my plates had small measurement errors (from slightly unconstrainted rectangles made while shortening one of the sides). While realigning my components, I learned that my PCB model had misplaced holes, which meant that I couldn’t trust it for measurements. I also lowered my rotary encoder so it wouldn’t clip into the top panel.
