Puzzle Cube

My friend modeled this and asked me to print it for him. He had made one out of wood years ago, but had lost several pieces. I honestly have no idea how to build it, but it sure looks cool when it's done!

You'll need to print 36 of the main piece and 2 of the notched pieces. This puzzle is pretty forgiving. It's easier if your tolerances are tight and the pieces are printed to their exact dimensions (because they stay put a bit more easily), but having them slightly smaller or larger shouldn't be a huge deal. If anything, I'd say err on the side of having the pieces be a tight fit.

You should be able to scale up or down as you see fit.
