Filament Clip for 3mm Filament

--> Check the remixes! There is a new Version here: http://www.thingiverse.com/thing:191487

I was inspired by Madox who did a nice little clip for 1.75mm filament (find that one here http://www.thingiverse.com/thing:12516 ) . I think this is a really useful thing but I only have 3mm Filament - so I decided to make a 3mm version. Still needs to be tested.. didn't print it by now. Idea is to clip the filament in instead of pushing through the hole...
--> I changed the overall height from 10 t
