Raspberry Pi Camera Mount

Mixture of the Kevinlo's original camera mount and Dizzee78's back with holes for heatsinks, edited by me to add a slightly larger tripod nut hole.

Just the front, back and tripod mount, not the Kossel arm etc.

I've included the FreeCAD source of the tripod nut bit as that's the bit I edited and I hate designs that only provide STL files.

Seemed to come out a bit better using ABS - with PLA the hexagon nut hole wasn't very symmetrical.

I printed the tripod nut part both with the nut hole on the bed (no supports) and with it sideways on (with supports) and it made little difference.
