Official Creality 3D All Metal MK-8 Extruder Feeder Drive Aluminum 1.75mm for CR-10 Ender 3 CR-10S

This is the MK-8 style extruder feeder drive made completely from machined aluminum. This part serves as a replacement for the molded plastic or 3d printed version that many 3D printers come stock from the factory with. The original plastic feeder is prone to wear as the filament is pulled into the feeder if the filament is pulled from above or below the intake. It will effectively "saw" at the plastic over time. The filament intake on this model is beveled as well, to prevent scraping the filament as it is pulled into the feeder which is a common problem among some cheaper all metal feeders.
