The QueMar is a custom hi-profile case for the Quefrency rev2.
Switch plate is 3mm thick to reduce flex in the final assembly. I found that with this thicknedd, no PCB support from the base plate is needed, it's plenty enough rigid. Two versions of the switch plate are available, one matches the default design from Keebio's Github and the other has the leftmost notch in the space bar area of the left hand removed. I removed it as some layouts don't need it and it causes a miss-alignment of the 1.25 switch placed there.
