This is a complete redesign of the Floppy Emu enclosure by Eduardo Correa Lima at Big Mess o Wires (see here for the inspiration).
The original has a few issues, notably the fact that the four buttons keep falling inside the box. Also, I was not a fan of the esthetic, no indicators, no fillet or chamfer, so I added all of this. Here is the OnShape project.
To create the light pipes to bring the LEDs' light to the front, use a piece of transparent filament. Melt one of the extremities to create a transparent dome (I used a hot air soldering station, but a lighter works too) and fit the filament in the hole, cut it to size, and glue it in place with a drop of super glue (or melt the other side with a soldering iron).
The box is held closed by four 2.5 mm x 12 mm screws.
The filament I used is eSun ePLA-Matte Light Khaki that almost matches the famous Apple beige (#C2BDB0).
After 500 hours of printing with the original nozzle, I think I need to buy a new one...
