I wanted a poop bin which could hang off the printer itself, and be easily removable if needed. Also wanted a higher capacity than existing solutions.

The mount gets screwed into the existing screw holes. By default the printer has 6mm M3 screws/bolts, this requires 8mm. The Qidi screws are coarse threads, but my fine thread bolts worked fine.

If folks want me to further increase the capacity, just let me know.
