The practical filament cleaner is 30mm long and can be clipped on very easily.
The resistance is so low that the filament feed is not hindered.
Reason for use:
Since most filaments are made of plastic, they are often statically charged and attract all kinds of dust from the filament holder or work area.
The filament cleaner wipes away any lint, dust or other debris before the filament enters the extruder and nozzle of the printer.
How it works:
As the filament is pulled through the cleaning clip, dust, hair, small plastic or other material shavings are wiped off the surface of the filament.
