Do you have old, unused consumables or leftover material whose dust not only affects printing quality but also increases the risk of clogged nozzles? Following the principles of simplicity and material savings, I designed a consumable cleaner that requires only 1.9g of material and can be reused. It fits standard fluoropolymer tubes with an outer diameter of 4mm, which can be connected to any location such as the printer’s feed port or the rewinding device used by @Sergiu_I to rewind the consumables and handle the bent ends.

It is easy to use—simply insert non-woven fabric or sponge, then pass the consumable through.

This is dust that falls off after brushing against a spool of consumable material, significantly reducing the risk of a clogged nozzle.
