Direct Drive Spool Holder for 2020 Extrusion

thingiverse

This is a basic spool holder that I designed to orient the filament feed direction for a direct drive. Included are two different roller lengths: a single roll and dual roll setup. In theory this could be used on a dual extruder printer, but I am simply using it for extra storage. The arms are designed to fit over 20mm (2020) aluminum extrusion, and it uses M4 bolts and T-nuts to hold it in place. The Elegoo Neptune 2S that I installed it on used these fasteners for the previous stock spool holder, so they are reused in this design. If you'd like to use this design but do not have the fasteners, the bolts are M4 X 10mm and the T-nuts are included as an STL (print at 105-108% scale). The holes in the sides of the arms could potentially be used in conjunction with some plastic self tapping screws for a camera or lightbar mount, but I have not gotten around to designing either of those yet.
