CAD for 3D printer prototype production

I have a patent. I got it myself. It was not easy, but I did it. The next step is producing prototypes to present to interested parties. That requires engineering skills, CAD, etc. I will need a NDA signed. I have no money. But I can pay a reasonable fee. The device is very simple and resembles a toothbrush. So, if you want to get in on it, call me. 512-652-8238
