The controller may be assembled with 3D printed parts, described below. The enclosure has three parts: a lid, a box and a NeoPixel diffuser.

The box has mounting holes for the Feather and RS232 breakout. It also has cutouts for the DE-9 connector and USB port.

The lid has a cutout above the NeoPixel on the Feather. This allows the NeoPixel diffuser to mount and glow, letting you know the BLE connection status.
