Filament cleaner for Prusa i3

thingiverse

This part is installed on the extruder (check out the photo) to remove dust or debris from the filament before it reaches the hotend, preventing any blockages that could cause problems. As a makeshift cleaning sponge, I used self-adhesive foam strips for doors and windows - you can easily find these at your local hardware store. The part was designed using SketchUp software.
