Im a mechanical engineering student in Montreal. I have more than 8 years in 3D modeling and now 2 years in 3D printing. I can help you create your idea from the ground up. I use Catia V5 and im really good with it. Im a lot quicker than other students right now. Now 3D printing is used for rapid prototyping, It can also be used to make a mold out of it. I can also recreate an item that you can't find anywhere. Its called Reverse Engineering and it helps a lot of people around me. Im sure I can help you too with your project.
