This is a 12-key 'macro'pad with an OLED display and LEDs underneath the keys! I plan on using this as a numberpad, with extra keys (calculator, gamebar)..
These were made in KiCad. There are two layers in this PCB. The top serves as the signal plane while the bottom serves as the ground plane.
Here is the assembled piece within AutoDesk Fusion 360! I was unable to find 3D models for the LEDs. The microcontroller also wouldn't export to Fusion360. Below I attached the KiCad PCB model and the Fusion360 model.
I separated the model into two pieces to print.
