Faberdashery Spool: easy-print + light remix

If you want to print or remix this thing also check out the **instructions**.
I like 3DMakeMe's design as it's functional and goes well with his/her Spool Stand (http://www.thingiverse.com/thing:296971 / http://www.thingiverse.com/thing:370344). I found it hard to print though: the almost horizontal overhangs on the forks never turned out well on my printer.
I redid the design in FreeCAD trying to copy the original as accurate as possible. Mostly round metric numbers made that easy.
