Minisynth 32: 50% scale mt32-pi case

See https://github.com/grantek/minisynth32 for PCB Gerber files, source files for the 3D models, and build guide.

The project consists of the 3D-printed shell, a Raspberry Pi running mt32-pi, and 2 custom PCBs: a hat for the Pi that mounts the rear panel components, and a front panel PCB. All components on the PCBs are through-hole, no surface mount soldering needed.

Optional USB version uses an Arduino board in place of the MIDI DIN connector.

The faceplate is trickiest to print, I prefer to print it standing up with "tree" support, although there is still some support that needs to touch the inside floor of the faceplate and needs careful removal. Optionally, it also prints well face-down, eg. if you want to cover the face with a printed label.
