I need a 3d image for a product design

Im stuck in a spot where I need someone to help turn my rough 2d .Sku file into a completed 3d file that can be used to 3d print. The completed file would also be used as the blueprint to develop the end product in stainless steel manufacturing(milling or injection). The design itself is patent pending and relates to the adult pleasure industry. I do not have the file attached here at this time though after a nda is agreed on I will send over and files and details.
