About this 3D model

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 files if anybody is interested. Aside from importing the catia files i have constrained the parts in Inventor as well as added / edited some elements ( work in progress) to reflect my home printer . all comments welcome enjoy
