This is the STL for the body of my custom numpad / macropad. Instead of the traditional “tenkey” layout I went with 19 keys + a rotary encoder for CW and CCW rotation as well as an addition button for a total of technically 22 inputs.
A more complete parts list is on GitHub but along with this print I used 19 Cherry MX switches, an EC11 encoder, an Elite-Pi / promicro RP2040 as the microcontroller, and copper wire with diodes to make a fully functional keypad. It's a very straightforward build and the QMK firmware is not especially complicated for getting the basics going. It works great and my dad and I have been using ours for months quite happily!
