Microfibre cleaning rope for keeping lead screws and threaded rods clean between regreasing. Wrap it around the screw, twist it into the thread and run it up and down to pull out old grease, dust and filament debris. Gets right into the thread groove where a rag can't.
Works on the Z lead screws in Bambu Lab, Prusa, Creality and most other desktop 3D printers, plus linear rods, rails and anything else with a thread that collects grime. Rinse and reuse.
