Folger Tech FT-5 filament guide

A simple filament guide I use in conjunction with CerHewer's FT5 spool stand, which I've found to be incredibly effective. https://www.thingiverse.com/thing:1705478 This guide keeps the filament centered and close to the spool, significantly reducing the likelihood of it jumping off. It can be securely fastened to the 2020 with one of the spare M5 bolts and T-nuts. The design allows for a quick print with no support needed in the default file orientation. A slit in the guide's circle makes it easy to slip the filament into place without cutting or reloading. For optimal results, move the spool holder as close to the guide as possible, given the size of your filament spool. While this solution may not be foolproof, it was a quick and easy fix that eliminated most filament tangles for me. However, large movements can still cause the filament to jump off the spool occasionally. This is often at the start of a print or when switching to a new spool.
