Robo3D Spool Holder V2

Version 2 of my http://www.thingiverse.com/thing:1064237

Filament holder made to fit a Robo 3D printer. You can mount 3 or more spools at once. Just need a 500mm (or 18in) by 10mm dia cheap wooden dowel or steel rod. Otherwise, print this 250mm rod (if your printer bed is large enough) and it can hold 3 Hatchbox spools or 2 JustPLA spools. Spools are free spinning pretty much and feeds directly into the feeder at the top on printer and into the extruder. This prints fast and easy. Simple and
