This is a filament guide for any 8020 based printer. I built it to solve the issues I had with my central mounted spool holder and extruder setup.
In all honesty, I only built this to solve a problem very specific to my Kossel setup, but I imagine other people with 8020 frames might be interested in this type of filament guide, so decided to push it up.

It should print great with default settings in cura. (Mine has some issues because I don't have a filament cooling fan on my printer; without one it's a little messy but serviceable.)
