Bowden Tube Filament Guide

A pivoting bowden tube filament guide.

The 1.75mm guide expects the bowden tube to be 4mm outer diameter and the 3mm guide expects it to be 6mm.

Mounts with two M3 screws onto whatever you like, so it should be easy to mount on aluminum extrusions or a printed mount adapter.

Print it, stuff a ptfe tube in there (or don't, whatevs), and bolt it on. The tube fit is tight, I didn't want it pulling through. I only got about 3mm into mine and I don't think it's coming out in one piece, which is fine.

Tested with a Prusa i3 Mk3 & Mk2S (mount adapter https://www.printables.com/model/141195-prusa-i3-z-frame-mount ) and it gives me a smooth kink free feed even when the extruder is at the top of the Z axis.
