Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4754454.

This sandwich skirt was designed to snap on between the PCB and the bottom case layer. The intention is to improve rigidity and help prevent the PCB and switches around the edges from disconnecting. There are two sets, one for 8mm standoffs and another for 7mm standoffs.

This was made for version 1.1 of the PCB design using Kailh hotswap sockets (indents in the skirt allows it to slide over Kaillh mounts on the underside of the PCB).
