Cornedeon based on Corne 3 PCB

Hard case for improved Corne v3:

Monolithic body with integrated top plate.
Corne v3 PCB for low profile switches plus 3 additional keys.
Selfmade hot swap sockets for additonal keys (Gateron in my case) [https://www.thingiverse.com/thing:7072872].
Type-C cable instead TRS.
