Universal Filament Spool Assembly

thingiverse

I designed a universal filament spool holder that would fit all sizes of spools, weighing between 1 kg and 2 kg, regardless of the manufacturer. I was inspired by dintid's excellent design, but his won't work with my printer setup, which can be found at http://www.thingiverse.com/thing:1775818. This design is intended for use on all sizes of aluminum extrusions and should be supported like in the photos, although it may also function well in various other configurations. I was surprised to find that it actually works surprisingly well even with heavier 2 kg rolls. It's easy to change spools. I've included files for a single-color model and for a dual-extrusion model, which I tested extensively after designing my printer's dual extruder. Parts Required: For Each Assembly: - 2 x 625zz bearings - 1 x M5 25mm cap screw (or regular screw), nut, and washer - 1 x M4 25mm screw, square nut, and washer
