SummaryThis filament cleaner is designed to be used on an M3D, of course it could be used on any other printer, The top is made so that a small piece of a paper towel or anything else that could clean the filament can be put inside the cylinder and clean it before is goes into the print head. Made for 1.75 mm filament but can easily be modified for any other size by cutting the hole the filament goes through,
