Welcome to our store! Cleaning: clean the dust. Since most products are made of plastic, they are usually electrically charged, and the cleaner can pick up all kinds of debris in storage or work space Material: The cleaner is made of foam high quality high density rubber that can easily slide over 1.75mm and 3mm diameters of ABS, PLA or other 3D printing consumables Universal: Most industrial filaments use closed tanks to solve this problem. Since most consumer 3D printers use open spool models which can easily cause clogs, it is important to address this issue. Improved printing efficiency: such as heater modules, extruders and nozzles become more complex and monolithic, maintenance or replacement costs are high, which can also lead to significant printer downtime. Consumable cleaners can prevent all this and improve printing efficiency. Package: Our package comes with 10 pieces of 3D printer cleaners, meeting your needs.
