3 Strand Braided Ring

So about a week ago, I had a *brilliant* idea, why not make a 3d printable thing that looks like it was braided together. Well, now I know why no one else has really done it. It requires an excessive amount of trial and error, and math.
(can't wait to see how I can port this into openscad...)

So yeah, about a week later, and a lot of time I should have spent studying/on homework later, I finally got this to where I am happy with it. The STL files are for a size 7 ring, and the Inventor ipt files include all the garbage for how it works, and stuff. I'll explain the how I designed this later. Hope you like it.
