A macropad is a programmable keyboard with just a few switches.
This case design holds 5 standard keyboard switches (14mm) and has room for a micro controller board with a 1.2mm thick PCB and a USB-C port (like the SEEED XIAO RP2040) which works great.
Created this basic macropad in tinkercad: tinkercad.com/things/0kz2FfeqGDC
You can download or change to your liking as I made the design public.
I build my own macropad using low profile Cherry MX switches and matching key caps that you can find over here…
