This upgrades the Creality Sprite Pro extruder to a reverse bowden setup. I have only tested this on an Ender 3 V2, so please feel free to remix according to your setup.
 

Note that one of the parts listed is an M10-0.75 x 5mm heat set threaded insert. This is where the PTFE connector screws into on the extruder mount. I used the one in the original Ender 3 V2 extruder (removed with soldering iron at 250°C).

In the future I'd like to make a version that uses heat set inserts for every PTFE connector mounting point, but for now the Coupler just uses printed threads.

I've attached images of the best print orientations.
