Ender 3/CR10 Hotend Bowden Fitting CORRECT THREAD PITCH

thingiverse

Replace that hotend Bowden connector before it fails! For use with a hotend featuring M10 .9mm pitch threading, such as the Ender 3 and Ender CR10. This design requires a length of PTFE cut using the cutting guide from OneBadMarine, but otherwise combines his insert onto the bottom of this connector. If you've tried the other popular adapter similar to this by Elproducts, you may have better luck with this design. It uses the proper Ender hotend thread pitch of 0.9mm, instead of the 1mm+ pitch of the Elproducts design. This adapter also includes an elongated hex section to fit a standard wrench and clear the stock Ender roller mounting screw that might otherwise interfere with the Bowden tightening nut. To complete this design, you'll need the tightening nut from the CR10 coupling remix reference.
