I tried to design a better cable chain PTFE clip after finding the ones I was using kept slipping after a while, because they get loose over time.
Mine has a zip tie to keep it tight.
The zip tie should go on the inside of the curve. You don't have to make it gorilla tight. This clip is going nowhere.
I also made the top area where the PTFE tube rides a little bit wider to give the tube a bit more freedom which prevents pulling as much.
Happy Printing!
