Description: brand new and high quality. Feature: 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. As most consumer grade 3D printers use an open Spool design, it is important to address this issue. 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. How it works: the anti-static filament cleaner wipes lint, dust, or other dirt before the filament enters your printer's valuable extruder and nozzle. Has two guides for 1.75mm or 3mm filaments. Can stay on the filament tip during storage to prevent it from self unwinding.
