Prusa XL double spool holder

I moved both filament sensors to the same side of my XL, so I needed to fit my 5 spools on the same side of the printer. These double rollers allow you to hang spools side by side on the side of the XL. The rollers are 75mm wide, but larger spools (such as 3kg ones) can use both rollers.

Designed this to screw into the 3030 extrusion using the same screw and nut as the original spool holder. Optionally, an extra M4 washer can be used.

Each roller needs 2x 608 ball bearings.

All parts can be printed without supports.
