Steven Karrmann aka skarrmann shared the Fract, this ortho keyboard with low-pro Chocs, Choc spacing, and self-encasing PCB a la his Horizon.
I wanted a simple wireless keyboard that could fit in my pocket, and Fract is the result – skarrmann.
Fract uses a second copy of the main PCB as a bottom plate, with cutouts for the components so it screws down perfectly flush. A top plate PCB covers the battery and the dev board, and provides cutouts for the reset button and power switch.

Choc V1, Choc spacing (18mm x 17mm)
