I’ve come across a few bumpers for the iPAC-2 Keyboard encoder, but I wanted an actual box. Not being able to find one, I drew my own.

Designed in two parts, the base can be printed in a different color, adding to the excitement.
To add a degree of wire relief, I used a piece of expandable weather-stripping to fill the gap, molds to the wires, and seals the box more.
This can be used with or without the shown weather-stripping

My application was for my Fix it Felix machine, so an STL of Felix is also included if you would like to include his likeness into your print. An embossed version is also downloadable for a Fix it decorated cover for single extruder printers.
