This all metal extruder is a great update for Creality printers such as the Ender 3, Ender 5, CR-20 Pro, CR 10/S/4/5.
New upgraded version of Extruder - see all pictures for complete details.
The stock extruder will wear over time and scrape your filament along the way. This extruder solves that issue. Overall, it is a much more robust part.
No firmware flashing required, and easy installation.
