I have always had tangling issues with all brands of filament but since I made this I haven't had issues!
All you need is the PTFE tube clamp thingy and around 4cm (1.5 in) of PTFE tubing. Just use a wrench and screw the tube clamp into the model and you're good to go
It's for my Creality Ender 3 but it may work on other printers. It's purposely a tight fit (you may need a lighter or heat gun) I had to hammer it onto the slot but it's not a big deal. After all, you don't want the guide shifting around!
The author marked this model as their own original creation.
