20 percent key base
thingiverse
I needed something quick with 24 keys, but couldn't find anything. I don't know much about keyboard drivers. Took the original "20 percent key plate" and made my own base to house two Arduino Pro Micros. The base is slight friction fit. You will need to flip the base 180 degrees in your slicer program. Printed the base on Ender 3 with 20% infill, no supports. Printed the key plate also on Ender 3 with 50% infill, no supports. Arduino Pro Micros use the keyboard.h library. Wiring/Programming based from the "Stream Cheap" project. Uses 24x Cherry MX keys. No changes were made to the original "20 percent key plate"
