Made this Filament spool holder to fit the Ender 3. The print makes it possible to line up 2 rollers on top of the Ender for easy switching color/material.

In each side of the "Filament middle" drawing, a 608ZZ ball bearing is installed to let it run without any resistance.

The first version included a PLA threaded rod, but was soon replaced by a 8mm steel threaded rod as i figured that the "End filament holder" worked as nuts. Therefore no need for steel nuts.
