First off, the CAD looks very nice. And the wheel is a decent design, except for the loop on the end of the spokes. It is very likely to snap there. And the part after it contacts the wheel is just adding weight.

Any chance of a different view angle? (If you have it on a picasa or photobucket, something like that?)
How wide is the wheel?
What's the width of the spokes? The depth?
Whats the bore diameter?

I'll get some other views of it. As I said my computer wasn't cooperating with me.

Yup, I wasn't planning on anything with these wheels except to learn a little about CAD.

If you have an experienced mechanical mentor available, ask her to show you how to do a "Finite Element Analysis" or to simulate what types of stresses will develop when you load it. This design should show some very interesting and informing results.

We have one mentor that does a lot of 2D CAD, I don't know how much 3D CAD he does. We have another College Student that took a class in it so I'll ask both of them when we start meeting again.

Then... create a light, snap-on decorative hubcap that fits onto that wheel and adds only trivial weight to the completed assembly. The hubcap's wow-factor is limited only by your imagination (and the audiences' ability to appreciate fine art ).

I'll look into doing something like that.


Edit:
Wheel is 1.5in deep, 6in wide
Spokes are .5in deep, .25in wide
Any other measurements you would like?
