Just another filament cleaner. This one can be snapped onto a filament without removing it from the extruder and it's made from a single solid piece.
I filled it with cotton but I think any fiber will do.
EDIT: I've added a half turn to help keep the thing on the filament. Not quite sure why the files are so heavy.
This is a small part with thin walls. Use whichever setting you feel comfortable with, I personally use 20+ wall layers and no infill.
