About this 3D model

Don't forget to hit the like button if this helps you :) A filament guide for the Ender 3 S1 gantry top rail, remixed to enlarge the hole through the eye of the swivel to be larger so its supports some PTFE tubing. OD 4mm is a nice snug fit. Idea is the filament runs smoother through the PTFE tubing and depending on how long your tubing is can help eliminate sharp corners/bends on the filament.
