Printrbot Simple Metal Spool Holder

I took the awesome design by mgx - http://www.thingiverse.com/thing:846520 - and made it so it would fit some of the unusual spools I had laying around.

This works with Taulman 910 1 pound spools with the small center hole and also with wider spools that some manufacturers use for the 1 kilo spools.

Simply bolts to the side of your printr for a real nice compact design
