The controller may be assembled with 3D printed parts, described below. The enclosure has three parts: a case, a lid and a small NeoPixel diffuser.
The STL files can be downloaded directly here or from Printables.
The case and lid snap fit together. The lid has cutouts and mounting holes for the Feather. The case has mounting holes for the rotary encoder and has space for a battery if you want to use the project without USB power.
