Ender & CR10 Filament Extruder Block with Threaded Coupler and Nut

thingiverse

The PC4-M6 Coupler that came with my Ender 3 was broken right out of the box. The extra one I got with the printer only lasted a few prints before it couldn't hold the PTFE tube anymore when printing. I found this genius printable coupler, but its threads were incredibly weak and broke when I tried to thread it into the extruder block. That's why I made this remix. With this new block, we no longer need to buy couplers. Just use a wrench to make it tight, and the PTFE tube will never budge again. An added bonus is that this block is friendly with flexible filament too. I trimmed my PTFE tube a bit and pushed it through to get it closer to the gear and bearing. I've been printing for several months now without any issues at all. I've even done many 10+ hour prints and several 20 hour prints back to back, and everything has turned out perfectly fine. Enjoy using this new coupler, and don't forget to share your creations with me!
