Filament spool holder (yes another one)

This is a universal-ish filament spool holder for an 8mm (or 5/16in) rod. You can add optional 608 bearings if you want it to spin smoother. The spline may have to be modified a bit depending on the inner diameter and width of the filament spool.

The Freecad assembly file uses the assembly2 plugin which you can get here:

This spool holder works well with http://www.thingiverse.com/thing:249094 which can be mounted upside down or right-side
