HAWKUNG 16 Pcs 3D Printer 1.75 mm Anti Static Filament Filters, 2 Pcs Filament Cleaner Block + 14 Pcs Resistant Rubber Foam, Wiped Off Debris and Dust for PLA ABS PETG or Other Printing Filaments

Total 16 pcs include: 2 Pcs Filament Cleaner Block + 14 Pcs Resistant Rubber Foam. Extra sponge can be used for replacement. Material: Plastic + Sponge Compatible: Compatible with 1.75mm diameter ABS, PLA or other 3D printing filaments. Reason for using it: As most filaments are made from plastics, they are often statically charged and attract all sorts of debris from around your filament storage or work space. This filament cleaner wipes lint, dust, or other dirt before the filament enters your printer’s valuable extruder and nozzle. The use of the the filament cleaner block will prevent your nozzle from being blocked by a buildup of debris and extend your nozzle’s and hot-end’s useful life. How it works: As the filament is pulled through the cleaner block, dust, hair, small plastic, or other material shavings are wiped off the surface of the filament. As hot-ends, extruders and nozzles are getting more and more sophisticated and monolithic, repair or replacement is costly and also can incur quite some printer down-time. This filament cleaner prevents all this and keeps you printing without interruption.
