V5 2020 Ender 3 filament guide / cleaner all in One. Single print
UPDATE: Made mounting bracket longer & put lip on top to keep foam in.
Version 5 - Single Print with mild support (use tree supports in Cura) & More Rigid Mount To Printer.
You only need to set supports for the extrusion connection area. Use tree supports if possible.
It really helps to prevent nozzle clogs by removing dust prior to filament entering extruder.
Simply insert a piece of foam and load filament.
Clean foam every week or so.
Filament used was CC3D Coppper
Use tree supports in Cura only in the extrusion attachment area. No need for supports for the sponge cup or sponge cup top.
