Tweaked a bunch of things:
Added snaps to the case so the top and bottom fit together nicely as well as a hole for the USB cable and expanded the socket for the rotary encoder knob. Also flipped the diode connected to the rotary encoder button and added mounting holes for the PCB. Learned how to use QMK to create firmware and wrote a basic script for numpad buttons and volume, still working out LED and OLED control functionality. Spent around 3 hours.
