Core-T Printed Wheels All Axis Spectra Driven

****Update 10-02-14***
I'm having issues with the wheels on my z-axis. It's looking like there's just too much slop with all the weight on 3060 extrusion. The 3060 is not wide enough either, unless a more constrained bearing is used. Right now I'm going to put some effort into a couple different linear bearing designs at the same cost of the 608 bearings. The 608 wheels are viable, but there's too much room for variability. I'm going to play around with some zinc plated BBs or airsoft pellets.
