SnapMaker 2 Filament Guide

Meant to be used with a [PTFE tube and a compression fitting](https://www.amazon.com/gp/product/B07PV8754Z/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1), makes it so that the filament can be pulled by the extruder, but doesn't go back and unwind the spool when the toolehead is returning to home.

If you don't want the unwind resistance, you can just use the non-threaded version without having the PTFE tubing.

BOM:
- 4 M4x10 bolts
- (optional) PTFE tubing, cut shorter to reduce resistance
- (optional) PTFE tubing compression fitting
