STS-Pi Pimoroni adapter plate

This is an STS-Pi Pimoroni ( https://shop.pimoroni.com/products/sts-pi) adapter plate to easily attach additional gear to the roving robot. Just zip-tie it through the openings.
The 3 different versions are:
-cutout for pi camera and Explorer pHAT
-cutout for Explorer pHAT
-no cutout (if you decide to directly solder the motor wires to the Explorer pHAT)
If you want to use the xplorer HAT Pro you might need to alter the cutout you I included the FreeCAD model as well.
