Anyone have a 3d CAD model of a 2 liter soda bottle?

I made one a few years ago (Sorry, I no longer have it). If I remember correctly, your easiest way to make the funky grooves is to revolve 2 planes at the angles you want the sides of the "bump" to be at, placing an identical curve on both and connecting the 2. Then you just round edges and such to make it look pretty. Once you have that figured out you array it 5 (I think) times around to have the "bumps". Same principle can be applied to the lower curves if you are not comfortable. Just remember... rounded edges are your friend, they can make the blending look very nice when used in the right manner.
