Filament Roller Guide

Filament guide for big rolls of filament that unspool as they roll. I use two primarily up to 6. The idea is one that directs the filament to the center of the spool on its way up to the PTFE tube. A second is as close to the bottom of the roll to direct filament back to the center that unwound. I have an additional four on each side of the roll that bend to the roll edges, but they are not really necessary.
