Rubiks Void Cube

Update 10/03/2013:
Turns out I didn't actually need to print the inner track ring with support, I thought the overhang would have been too steep but it turned out it wasn't!

Update 09/26/2013:
I've cleaned up the existing models and added a few beveled edges that should make it easier to maneuver. However, it didn't improve it as much as I would have liked, there is an improvement but not much. I've uploaded all the updated pieces with a '_v2' postfix.

Update 09/25/2013:
I'm in the process of updating some new, improved, models that have been cleaned up and rounded to make them move much easier. Once I print them out and am satisfied with them, I will upload them here as a version 2.

This is a replica of the Rubiks Void cube. It moves exactly like a normal Rubiks cube, except it has no core. The lack of the core is actually a benefit for us, though, since that means there are no springs or other vitamins to deal with. The entire cube, minus coloring the sides
