Prusa Air 2 filament spool holder

Inspired by other Air 2 spool holders (http://www.thingiverse.com/thing:35915) and using VeimoX 's catia files which i imported into Autodesk Inventor
i designed these spool holders to use the existing screw holes used for the assembly brackets.
Replaced the original screws with 30 mm long ones ( M4) to accommodate the brackets base thickness.
Uses M8 rod X 265mm long to support the filament spool + 4 X M8 nuts & washers

Quite happy to share the "Prusa Air 2" Inventor assembly / parts
