UpMini Filement Holder for the new Spools

The new spools from 3dSystems NZ come in a 1kg format with a wider load and different hole size that does not fit the supplied holder.

So I made this one with libraries taken from Thingiverse http://www.thingiverse.com/thing:27748 and http://www.thingiverse.com/thing:6021 to complete it.
