About this 3D model

This filament filter keeps the dust out of your extruder head. Just push a piece of oil wetted sponge through the base hole and then thread your filament through. Your filament will be cleaned as it enters the extruder head. Use one for each spool of filament and use the attached clip to keep your spool tidy when not in use. Versions for 3mm and 1.75 mm filament included.
