Low Profile 4x3 Raspeberry Pico (USB C) Macropad

I enlarged the original model to acommodate a Rpi Pico board, added some reinforcements to the walls, extra posts and another screw post to keep the faceplate from bending outwards

It is recommended to use very thin wire like enameled wire and hot glue to secure the board and button as the fixing method from the original was removed, in my case I soldered that button to the bootsel button of the board to program the pico without opening it

Regarding the print, I used PETG and the tolerances for the switches ended up being a bit loose so I also secured them with hot glue, previously marking the areas with some paint over the posts (as it can be seen in the images), to avoid collision between the hot glue blobs and those said posts 

Now for the software (and wiring diagram), in this case I used KMK following this tutorial guide: https://www.instructables.com/Pico-Based-Number-Pad/

Made it compatible with Raspberry Pico RP2040 board
