Features: 1. Stable material: The filament cleaner blocks are made from high-density sponge material, which can slip over standard 1.75mm and 3mm diameter ABS, PLA, or other 3D printing filaments smoothly, does not easily fall off the residue, and has a strong dust filtration capacity. 2. Reasonable design: All sponges are made with 1.5mm holes for the filament to pass through. The snap-on housing makes it easy to open, and in the for case of severe filament bending, you can open the casing and remove the sponge for the filament to pass through. 3. How to operate: The anti-static filament cleaner wipes lint, dust or dirt before the filament enter your printer's extruder and nozzle; When the filament passes through the cleaner, it will wipe off dust, water or other debris from the foam sponge to avoid clogging at the nozzle or being pressed onto the molding to form a crucible. 4. Widely application: The 3d printer filament cleaner can be widely applied with Direct-Drive and Bowden Extruders, wipe the dust, hair, small plastic, or other material shavings off the surface of the filament. 5. Package includes: 1 piece 3D printer 1.75 filament filters in black color, with dimension: 1.18x0.79x0.79in.
