A key with a cutout for a usb c female connection. This is taller than some key hosts due to the increased interior width to accommodate a usb c breakout board vs direct wiring to the trigger for more possibilities. The height allows for the board to fit in diagonally without having to increase the overall width of the key. This height is only about 3 mm more than standard. Should allow for most mechanical key triggers.

Note: this requires soldering wires to complete the key, usb c breakout boards, a mechanical key trigger, mechanical key cap (I just printed one), but no additional parts for the housing.
