Filament dust cleaner

thingiverse

Just another filament cleaner. Keep the filament dust away from the hotend. An additional part you need is a little piece of foam of 10mm thick. Print the cleaner. (Don't need supports) Cut a piece of foam as a circle slightly larger than the radius of the piece. Put the foam into the ring an use a cutter to cut the foam to the center. That's all. You do not need to remove the filament to put the filter.
