This design is to hold a mini wireless keyboard/mouse device as in the photos.
I holds the USB dongle and allows access to the power switch and the USB charging socket.
I use one of the keyboards for my Raspberry Pi's, it's really handy fo use with the Pi's which run Octoprint for the printers as I hate wires all over the place and sometimes a keyboard is needed.
The keyboard holder will sit nicely inside the lid so you don't forget where you put the lid in use.

Print instructions

This can be printed without supports at whatever layer height you like. I printed my example at 0.3mm for instance. The lid took about 3 hours and 1 hour 28 mins for the keyboard holder itself.

I've supplied the .stl and .3mf files. Feel free to edit/change the design.

This is an original, free design, you don't need to attribute it me even.
