  Hi Erika!

  I would sketch part of the shape and then pattern the rest of it as needed.
  Then model a cylinder and use Wrap command to wrap the sketch around the cylinder. Then you can use Law Extension to extrude the wrapped sketch according to the cylinder face. Finally thicken the surface and apply necessary blends or chamfers.

  Example made in NX10.

     Thanks guy! Sorry for the answer delay. There is just a problem: My NX is 9.0, and your .prt and .stp are in NX10, is it possible convert it? Or would u need save as NX9.0 version?

     Thank you very much to everybody!
