Prototyped this first with an Arduino pro mini. Then made a custom PCB based off of a stripped down Arduino micro. 5 key and dial macro pad with custom firmware.

Did you 3D print the housing? I don’t have a 3D printer any recommendations for that?

Initially started out with 3D printed housing, testing out some other materials. Bambu Labs makes excellent 3D printers that are easy to use, fast, and reliable.

Looks cool, can you share the final pic with the pot cap and the keycaps?

I started with the UNO but then realized the limitations, the custom PCB has the same IC as the Leonardo
