Printable Filament Spool

A printable filament spool with a standard 32mm centre diameter. 60mm diameter for filament wrap and outer diameter of 120mm. It holds 300-400 grams of filament.

After nebbian had some problems with his make http://www.thingiverse.com/make:166072, I've updated the design changing the following aspects: Increased the number of polygons so it's prettier, increased the clearances, incorporated holes in the centre and rim to secure the ends of the filament. The revised version of the stl has a v2 in the name.
