It is plastic money clip named "It's Money"! I designed it in Solidworks, I spent a long time perfecting the openings so it could hold a single dollar as well as a lot of dollars. I currently print them on a Dimension rapid prototyping machine out of layered plastic. I kept giving them away so decided I should make them my business card as well. I now have 3 different designs, one is plain, one has my racing team logo and the other has my contact info.
