I couldn't find a filament poop bucket that was both easy to remove/empty AND that would work with the Elegoo CC1 w/Canvas because the access port cable was in the way every model. My printer is on my work table backed up against a wall and I couldn't easily line up screws to let it hang. I needed something that could sit on the table and magnetize to the printer, so I decided to make one myself.
 

• It is designed to use 12mm x 2mm magnets (2)

It isn't perfect. The screw holes in the top of it don't line up perfectly because of the height of the model, but it works like a charm. This is my first time to make any kind of functional part in 3D. I used TInkerCad.

I hope it's as helpful to the community as it is to me!
