Pokémon Go Mapping ATV Bracket

I needed a conservatively sized bracket for my ATVs, allowing me to stack them fairly close together in such a way that they were enclosed. This is that design.

It is designed to take up to 10 ATVs, being X96Q Mini's, running the H313 chip (note that the S905W version will not fit as it has extra components which prevent the interference fit along the back edge of the board).

The board sits in a 3mm wide slot on the base which keeps it vaguely aligned, but up the front (or back) of the rig there is a 1.5mm wide slot, which with my printer settings provides an interference grip on the PCB itself.
