USB 10-key keyboard case

MassDrop sent supporters of the first ErgoDox Infinity and Infinity 60% keyboard drops a special gift of an external 17-switch 10-key keyboard PCB. Unfortunately it lacked a case. The PCB is designed for PCB-Mount Cherry style switches, but that doesn't stop anyone from using plate-mount switches with an appropriate case.

Hopefully this is a good start for a plate-mount case for the external 10-key.
