Splanckle 40% Handwired Ergo Mechanical Keyboard with Rotary Encoder

I really liked the Planck mechanical keyboard. After using a Sofle for some time I liked that it was a split keyboard and the thumb keys for Enter and Space. I didn't really have a need for the number row from using the Planck and did not see a board that met my needs. So I designed a plate to hold MX switches and some rotary encoders. I used solidcore wire to wire up the matrix's to the pro micro's which hold the MCU and the OLED in place pretty well. When designing the case to protect the wiring I added a hole to hold the TRRS Jack in place so it would not break the solder joints. I used Pro Micro's for the MCU's and standard OLED's that sit on top of the MCU's. I ended up only using one M3 screw to hold the plate and case together. I used heated screw inserts pressed into the case to hold the plate to the case.
