I built A Better Poop Chute (ABPC).
This Bambu Poop Chute holds onto the back of the printer with magnets only, and has smooth radiuses throughout to ease any chance of poop constipation.
Magnet size is 8mm diameter, 5mm tall. They can be sourced from eBay/amazon etc, and glued in with superglue/CA etc.
I printed mine from the Magenta PLA that came with the Bambu X1 Printer and it worked fine.
I added support for a 30° overhang threshold, but you may want to go even more as the big radiuses outer edges start pretty flat.
The author marked this model as their own original creation.
