Anycubic I3 Mega Pro Spool Upgrade tuned

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5458879.

Thanks to @ringo2k for the base model. I added side panels to prevent the Filament Spool falling off the Holder ;)

You need 1 8mm rod or M8 rod and two normal 608Z ball bearings.
