Ender 2 (CR-2) Extruder Chamber

thingiverse

A coupler made from a combination of an extruder and Teflon tube on the Creality CR2 (Ender 2) consists of plastic (female thread) and metal (male thread), respectively. Frequent installation or reinstallation can cause significant damage to the coupler, which prompted me to create a simple extruder for my Ender 2. A direct installation of a metal union with Teflon tube into the plastic extruder chamber is possible without using any tools and extra parts. Following this setup, a tube clamp is required to prevent the tube from detaching. In case of an emergency, the cover of the extruder chamber can keep the coupler in place. I am now using this extruder together with "Snap Lock Extruder Sleeve" created by danbear, which allows for convenient handling and installation of filament with just one hand.
