About this 3D model
A Rework of : http://www.thingiverse.com/thing:302633 I changed the design a bit, added support, should print without warping, Mine did! Print at 25% infill at .2mm layer height for best results. Also added a stl for bearing extensions for 608ZZ bearings so you can use smaller spools on it. Branded with my Business Name, MakerFront. Cheers!
