Creality Ender 3 Bowden Extruder - Remix

I remixed this from the files on Creality's github as I felt the stock extruder did not apply enough tension. Now you can put a M4 bolt through the lever and put a nut on it to add more tension. I have also made the filament enterance hole 4mm so you can push a piece of PTFE tube into it to make the filament path better if you are using the stock top mounted filament spool holder.

Printed at 50% cubic infill from PLA. ABS is probably best if used in an enclosure.
