This dual geared extruder will ensure smoother feeding on your 3D printer. Comes in an all aluminum design, being stronger than the original plastic extruder block which commonly breaks causing extrusion problems. Dual gears applies more surface area to the filament (1.75mm) giving it better grip.
** Please double check measurements. These are made to suit stepper motors with a removable gear. This will not work with stepper motors with a pressed on gear. **
