About this 3D model

I had one of these when I was a kid, and my son is currently obsessed with tornados....so, 3D printer to the rescue! Add two bottles, some water, spin once and enjoy! I would recommend printing with 100% infill to avoid leaks. If you like this project or want to know more about 3D printing, check out my new book "[The Makerspace Workbench](http://shop.oreilly.com/product/0636920028147.do)" from Maker Media!
