21 Key Mechanical Numpad

A 21 key hand-wired mechanical numpad. Designed to be used with a YD-RP2040 Raspberry Pi Pico, but I've included the STEP files if anyone wants to tweak it to hold a different microcontroller. I'm personally running KMK firmware on it (there's a great tool called pog that makes it super easy to program your keyboard), but it can also be configured to run with QMK if you want.Assembly:For easier printing, I've made the case_top and the switch_plate separate pieces that fit snugly together.The switches and stabilizers should click into the plate easily. Heat set inserts go into the four holes in the back of the case_top. Since the Pico has more than enough pins, I just wired each switch directly to the board and daisy chained them all to a ground pin. I used double sided foam tape to secure the Pico to the case_bottom.The case is then fastened together from the bottom with four M3 x 16 countersunk screws.
