I've seen a few pokeballs here on Blendswap and I'm a fan of Pokemon... So I threw this together in about 30 minutes.
The materials are pretty damn simple and so is the geometry. I tried to make this months ago when I first started 3d modelling and failed miserably. After revisiting it, I'm happy and I hope you guys like it.
You're free to use it and have fun with it. Credit me if you use it though =]
