I'm going to start uploading some models onto this blog very soon.  I will have lots of pictures and stats as well as the 3D model.  If you are interested in viewing the model here is a free software which you can use to view/measure and explode the yo-yo.

It is safe and free, I use it all the time at work.  All you will be able to do is view it, sorry no manipulation possible.  But, it is still neat.  Check back soon for some prototypes.

*update 9/21* It turns out I can't upload any 3D models to the blog so if you still want to view the model shoot me an email and I will send it to you.
