All Metal MK8 Extruder Feeder

This is an all-metal extruder upgrade for MK8 style extruders. 

This is suitable for most 3D Printers, including Creality machines.

Consistent extrusion is a critical part of having consistent, quality prints. 

The standard plastic extruder feeder can often have a lack of tension and consistent pressure. This is definitely a worthwhile upgrade.
