Creality Ender 3 Bowden Extruder - Remix

thingiverse

I remixed this from the files on <a href="https://github.com/Creality3DPrinting/Ender-3">Creality's github</a> 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. You will need to print both parts, as the filament path is slightly higher in this version due to making space for the M4 nut in the rear of the lever. Uses all stock Ender 3 extruder parts. Apart from 1 M4 nut which holds the idler bearing to the lever, and an additional M4x15mm bolt and nut which acts as the spring retainer and adds extra tension to the spring. Fusion file included.
