A coupler of an extruder and Teflon tube of the Creality CR2 (Ender 2) is made of plastic (female thread) and metal (male thread), respectively.
As expected, frequent installation/reinstallation can cause serious damage the coupler. So, I decided to make a simple extruder for my Ender 2.
A metal union (Fig. 6) with Teflon tube is directly installed into the plastic extruder chamber (Figs. 1-5) without the use of any tools (eg., wrench, screw driver etc) and extra parts. After installing the metal union, a tube clamp (Fig. 7) is needed to prevent the tube from releasing.
In case of emergency, the cover of the extruder chamber (Fig. 8) can keep the coupler from detaching.
Now, I am using this extruder together with "Snap Lock Extruder Sleeve" created by danbear (https://www.thingiverse.com/thing:2779130).
It is convenient to handle and install filament with only one hand.
