This Aluminum MK8 Extruder Upgrade Kit replaces the original plastic extruder on Creality printers.
If you purchase a Creatity printer, you will get a lot of value for your money. There is one small downside to mention, and that is the original extruder. It is made of plastic, and because the filament constantly passes through it, the filament will eventually wear down the plastic. This has detrimental effects on the print quality. The Aluminum MK8 Bowden Extruder Upgrade kit is a direct replacement. It is very easy to install and is a must-have upgrade, for example, for your Creality Ender 3.
