A1 mini poop bucket with very tall side wall to catch every poop no matter what height the print head is at. I designed it not to take too much extra space to the left side of the desk. And with a magnet dock you can get a perfect alignment every time putting it back in place. Add a gantry alignment sign on the inner wall of the top piece for you to easily align the bucket when installing the dock or if you don't want to use the dock at all.

BOM (Only need these if you want to use the magnet dock):
6*3 or 12*3 magnets - 4pcs
20mm wide at least 1mm thick double sided sticky tape - 1pcs

Change log:
10/20/2023: V1.1; Add 12x3 magnet version incase the 6x3 magnets are not strong enough for you; Decreased the depth of sticky tape cut out to 0.5mm.
