DONT CALIBRATE WITH THIS INSTALLED!!!
Works fine for prints but having the bed at the back and the hotend to the left will catch the mount/gopro.
The existing PrusaMini GoPro mounts are lacklustre and too unstable to be used adding wobble and possibly cause print quality implications.
This design slides onto the bottom left corner of the bed and is offset so the gopro (hero black 7 tested) lens is positioned in the middle of the corner.
Chamfers added for design however the actual part uses the thick overhanging parts and mounting screw to keep it stable.
Designed in Fusion 360 but significant amounts of jank and offsets used, if its popular enough ill redraw the sketches to the final design.
Thicker one uses a 10mm m3 bolt.
