Filament Guides Upper and Lower , Single and Dual Gear Extruder, Ender 3
thingiverse
Had wheels, axles and bearings left over from work on this [adjustable filament spool holder](https://www.thingiverse.com/thing:3648130/) and wanted not only to reuse them, but to have a matched upper and lower guide with lower guide at suitable height for a dual gear extruder. Lower guide brackets included for single or dual gear extruders. Brackets and axles have retention and anti-rotation features not visible in photos, please see STL files. You will need 608ZZ bearings. Thanks to [Stauffen](https://www.thingiverse.com/stauffen/designs/) for the brilliant idea of overlapping the filament insert gap in the z direction for greater filament entrapment. Realize there are hundreds on remixes of these designs already, hope you find this one useful
