Bowden Extruder Coupling PC4-M5 for SW-200

thingiverse

This is a remix of Improved Tapered thread Bowden coupling PC4-M6 by spool2kool. None of the printable connectors I found seemed to fit my printer's extruder, so I took some measurements of my connector and modified one of the Things to work. Spool2kool's design came pretty close to what I needed and included the lock nut as well, so I used it as a base for this remix. This should fit a Sooway SW-200 and its clone, the Kingroon Kp3, though it might also work on an Ender 3, as well as any others that use the same blue PC-M5 connector. I recommend printing with a brim at slow speeds (25-30mmps) at a layer height of 0.15-0.2mm, as that worked well for me. This thing holds pretty securely, though it does need some minimal post-processing of the filament hole. A small drill bit, a circular file, or even a pair of thin tweezers can be used to enlarge the hole just enough to prevent any friction with the filament. I'm also including the nut from spool2kool's thing as it's both necessary and helpful to have. Hopefully, that's okay. Happy printing!!!! Edit: It seems Thingiverse just added a bunch of junk to the images folder. Nothing I can do to fix it. My apologies. Edit: 1/22/2020: Added a V2 version that has a longer bolt head area. Should make turning and adjusting it easier. Also, slightly increased the inside diameter for the filament hole, though I don't know if the difference is enough to come through in the print. I don't want to make that spot too thin.
