Ender 3 Side Spool Holder

Takes the spool from being mounted above the printer to being mounted on the side where it feeds directly into the extruder. I wanted to make this as easy to install as possible, so it simply reuses the 'stock' mounting screws and trapezoid screw things. The actual mount simply slides into the rails, so you can adjust the position to be where you want (forward or backward).

At 25% infill it took me just under 2 hours to print.
