Upgrade the red extruder:
The all-metal MK-8 extruder drives 1.75mm filament. It makes loading filaments easier and smoother without worrying about scratching or breaking the filament. This extruder drive is compatible with almost all models of 3D printers. There is no need to replace stepper motors or other mounting hardware.
Wide range of applications:
The upgraded metal extruder is compatible with almost all models of 3D printers (Ender 3/3 Pro, Ender 3 V2, Ender 3 Max, Ender 5/5 Plus/5 Pro, CR-10, CR-10 V2, CR-10 Max, CR-10 S4, CR-10 S5, CR-10S, CR-10 Plus, CR-X, CR 20/20 Pro). There is no need to replace stepper motors or other mounting hardware.
Very easy to install:
Unscrew the old original plastic extruder and screw in the new metal extruder, ready to start printing.
