iGo3D Filament Spool Clip

I tried several of the other designs and none was a great fit, so I made my own. I also have added Solidworks part file for tweaking the sizes a bit for the perfect fit, if needed.

This is supposed to work on spools from the German premium filament supplier iGo3D.com. This is for the 1.75mm filament.

UPDATE 12.01.2014: Added 3 mm version. The previous was just the 1.75 mm version. I cannot test it since I have no 3 mm filament but it should work just fine.
