Ender 3 Side Mount Filament Spool Holder (Screwless Design)

Redesigned Ender 3 side mounted filament spool holder with V-slot extensions to mount directly onto the extruded aluminum base.

It is a TIGHT fit. I had to scrap the edges of the notches a little bit using a utility knife to get it onto the base. Then used a hammer to gently tap it into the desired position. You will have to temporarily remove the plastic end cap on the back of the aluminum base to install this mount.
