About this 3D model

This is a design for a small on-printer waste bin for small flashes of waste filament and parts that build up during many prints. It simply sits on top of the extrusion and slips into the slot to secure it and can be lifted off for clearing out the waste bin. There are two version, one for 15x15mm extrusion profiles and the other is for 20x20mm profiles (untested). Print it upside down and without supports.
