Adjustable Heavy Duty filament spool for Ultimaker

This thing has moved to Youmagine https://www.youmagine.com/users/jensa so I don't also get sued by Stratasys...

This is a remix of the brilliant Adjustable Heavy Duty Filament Spool (http://www.thingiverse.com/thing:19122) by @KillerGardevoir for use with the Ultimaker mount (http://www.thingiverse.com/thing:33461) made by @fluxline.

The arm and hook are like on the original, but the Hub has been redone to work with both 3 and 6 adjustable arms as well as to fit the Ultimaker mount.
