The Creality Ender 3 V2 is a remarkable machine and had plenty of great upgrades from the predecessor Ender 3 and Ender series. However, it has a flaw on the extruder as it is made from plastic and often breaks. This video shows how to upgrade the extruder from the plastic one to the metal extruder.
You can easily purchase the Metal Extruder from online eCommerce stores, however if you are getting your Ender 3 V2 from Cytron technologies, the metal extruder is included. https://my.cytron.io/ampp-creality-ender-3-v2-3d-printer-diy-kit-unassembled-uk-plug
