I modded the great design by DaGov to accomodate for bowden fittings I had laying around (from my Voron-Projects) as well as improving printability.
The only part I changed is the back extruder part. The remaining parts can be used from DaGovs design.
In the fotos / pictures you can see a crack in one of the bowden-insert parts. I have since adjusted the tolerances of this area to reduce the crack-risk.
These are the bowden fittings I used
