Jorne split keyboard thick plates

This is a set of two plates for a Jorne keyboard by joric ( https://github.com/joric/jorne/ ). I've remixed original corne plate design by lw97 to include additional pinky button of jorne.

The files can be mirrored in slicer to get a set of plates for the other hand. The files here are for the right side. Pay attention to the lip on the midplate - it should probably be printed with the lip on the buildplate, and the side with the lip is gonna be the side facing the keycaps in the end (so the switches click in on top).
