This a sandwich-mount case and plate I designed for a handwired ErgoDash Mini. It's my first time doing CAD, feel free to submit PRs or let me know if you've got any suggestions! Also, I would appreciate it if you could attach a link to this page if you print this case and post photos of it.
Some notes about the files:
- Only use the KMK config files as reference. They're pretty messy as I had to compensate for some errors I made while handwiring.
- The M3 screw holes are a little tight, so it might take a bit of effort to get in. I used an electric screwdriver, screwed it in all the way and then used reverse mode while pushing it out but... it's easier to just widen the hole.
- The holes were designed for 3mm x 4.5mm (h x d) heat-set inserts
- The plate is designed for female header pins 8.5mm tall.
- The case was designed for use with the Pi Pico.
- The TRRS cutout is a little narrow and not all cables will fit. Check the diameter of your TRRS cable termination first.
- The mounting holes above the Pi Pico were originally designed for screwing in either an acrylic cover or a module with an OLED screen, but it is too thin and I don't expect it to hold up well. There isn't much clearance underneat it for an M2 nut either.
