Official Creality Upgrade Aluminum Parts MK8 Extruder Alloy Block bowden extruder 1.75mm Filament for CR-10 Series. Ender's Series
The MK-8 Extruder was the first upgrade that I performed on my Ender 5 and I must say, its awesome! Great item to pick up! Would recommend it.
This alloy extruder is absolutely awesome improvement to my printer (Ender 5). Original plastic version broke after two weeks printing. Delivery took very long time. One month (!!) from order to Finland.
