Based on original ErgoTravel by jpconstantineau here

- Kalih Choc switches only (no MX switches) - Tighter key grid (only 17.5x16.5mm Kalih keycaps supported) - Removed LEDs because I was lazy - One extra key - 10 XT60 connectors - Foldable - Connectable (if you connect the two halves you don't need TRRS cable)

Build process is pretty similiar to original ErgoTravel.
