I am building a macropad called Zenithpad. It is a 6 key 2 rotary encoder macropad. I used KMK for the firmware. The CAD uses 2 parts, the top and the bottom. Both parts are secured using 4 heatset inserts and 4 m.3 screw bolts. I require funding to get a soldering iron, but I already have a 3d printer.
