Filament cleaner

I have one dirty roll of filament so I created a cleaner for it. I used ~ 25 mm x 65 mm piece of microfiber cloth folded in half and rolled around the filament. Seems to work great and after few prints the microfiber cloth has caugth a lot of dirt from the filament. This uses PC4-M10 PTFE Connector and has threads for it both sides but I think you can use this without the connectors as well. I would not use this with ams as it could block the filament change.
