3D printed PB spool stand

thingiverse

This is a 3D printed spool stand for the printrbot. It is used to hold the plastic spool in the side of the printer to provide a smooth unrolling action. You need 4 roller bearings and 2 bolts and nuts (optional). Instructions This object is a derivative from http://www.thingiverse.com/thing:29594. Is an spool stand intended to be printed instead of laser cutted (for those who do not have a laser cutter). You need 4 roller bearings (608) and M3 bolts and nuts (optional). There are 2 different pieces, base and arm. You need to print 1 base and 2 arms that fits perfectly. Be careful with the dimensions. I design this pieces for my plastic spool (120mm width), but maybe it'is not correct for yours. By the way, I provide the parametric scad file for changing the parameters, such as width, height, bolt diameter, etc. In the base the word "DOWN" was written to put this side down :-P. I've imported the letters from this thing http://www.thingiverse.com/thing:15198.
