Deik Robotic vacuum cleaner weel gear

If you plan to print with PLA, use the single piece, not the assembly
My setting:
100% honeycomb infill.
4 layer for external, internal, top and bottom.
0.12 layer height
Support
Raft
Generic low cost PLA at 195°

Your printer MUST perfect calibrate in all axis (x,y and z) otherwise parts not fit well.
