Summary This is a square bracket to mount a raspberry pi to 20/20 extrusion. The screw holes are counter sunk so flat head screws will fit flush. This piece goes along with 2 other parts to mount your octopi to the frame of your delta printer. See other submissions for camera mount and camera arm. Print Settings Rafts: No Supports: No Resolution: any Infill: 40% Notes: I printed this 40% infill as it will be holding a raspberry pi to a delta printer and I wanted it to be stronger than normal.
