Remix Prusa i3 Spool Holder

This is a remix of Prusa i3 MK1 & MK2 Spool Holder V3 - Quick Change. I had the problem that the Main supports was move and the Spool wasn't stable.

I modified one bolt making it more longer (118mm) and I printed 2, and I printed 10 nuts (instead 4) to arrange the main supports let it free the bearings.
