This is for those who want to guide their printers poop to below… no not onto the floor, that's disgusting… into a bin/ collector behind or under a desk for example.
 

The side that would normally touch the printer was removed in the design to reduce the chance of blockages and to create a larger gap for the poop.

It takes 6 x 10x2 mm neodymium magnets with a tiny bit of glue, the holes are very snug, or you could always use double sided tape instead of magnets.
