DHF Printrbot Simple Filament Spool

I remixed a version of http://www.thingiverse.com/thing:387313 . It's less of a handle now and more of a filament holder.

I flipped the filament arm so that the raised edge will help hold the filament on.

I also shortened the height of the stand so that it prints faster.

I put the filament arm on the opposite side of the holder to help with balance.
