DIY 3D printed case for the Yushakobo Primer61 PCB I got in Japan over the holidays. I didn't buy one of their BLE Pro Micro boards, but had a Nice!Nano clone, so I learned just enough ZMK to port it over and use it wirelessly. More HERE. Not my cleanest print, but I'm happy, and pretty stoked I didn't set it on fire trying to use an unsupported MCU with a wireless firmware.
Ooo! 24 function keys!
