M6 Filament Guide

A filament guide for enclosure. My enclosure (pictured) is made of full 3mm acrylic. First version of this is just a smooth tube, I just don't want the filament to be scratched or cut by the acrylic. The smooth tube will pop out everytime I change filament, that's why I design this, which turns out to be great.

You'll need M6x1 tapping bit. Printing is easy, no support needed, just go slow.

This has 4.1mm inner hole, so you can fit in PTFE tube too.
