Extra spool holder for Rostock Max V2

SummaryAn extra spool holder for the Rostock Max V2, you can use it for dual extrusion or for another printer. You'll need a 608ZZ for the underside of the top piece. Simply slide the spool holder on to the base of the existing spool holder. This is based off of my other unattached spooler-holder: http://www.thingiverse.com/thing:756989. Feedback is always appreciated. Released through my company Northern Layers: http://northernlayers.com
