filament cleaner

The filament cleaner is designed to prevent dust from reaching the heating chamber of your nozzle, minimizing the risk of obstruction. For more information, consult the instructions. To use it, wrap a piece of fabric around your filament and secure with a rubber band (as depicted in the photo, although plastic foam is not ideal). Insert the wrapped filament into the main compartment of your part. Regularly remove it, unravel the fabric for cleaning, and reattach if desired, especially to your extruder cables (as shown in the picture).
