a simple filament cleaner

Cut a piece of sponge or foam into pieces and put it in the filament cleaner. Pull the filament through and push the filament to the print head on direct drive and on Bowden extruder in front of the filament entrance.

This version does not work with the AMS because the filament movement causes the cleaner to twist on the roll!

If the filament cleaner is desired in an upgrade version, I will try to work on an AMS compatible version.
