Remix of nilson_fx's remix of poop chute basket. My remix is a very little bit bigger and has enclosed magnets.

You can put 3 magnets with a maximum size of 10x3mm inside and enclose them. In the slicer, just let the printer stop for the appropriate layer. Then put some glue in the holes (so it won't rattle) and the magnets. Then continue printing and the holes will be sealed with filament.

Maybe test in advance if the hotend or the nozzle are magnetic. Otherwise there could be a medium sized mess. I've printed it with a MK3S+.
