I wasn't happy about the drag chains that I printed before for my Ender 3, the hinges didn't feel nice, the print never looked good, then I decided to make my own version using different concepts. After several tests and prints, I finally achieve a design that looks nice and works smoother. I plan to make more for the other Ender3 parts too.
The hot end part is supposed to snap in place, the distance between axis is 40mm, if yours is different let me know the distance and I will make an updated version.
I used 14 links for my Ender 3, maybe yours need more or less, that's on you.
Something that you should have in mind, with this cable chain setting, you lose some Z-axis space.
Only the "support-2.STL" part need supports.
