It was bound to happen of course. When 3D printables files are available online for free and easily shared there was always going to be someone who would be willing to take advantage of that freedom. 3D printing technology is going to completely alter copyrights, trademarks and IP law dramatically over the next few years simply because there really are not a lot of ways to stop people from duplicating, and in some cases stealing and taking credit for, 3D content. Currently there are only two real defenses that 3D model designers have to prevent their work from being stolen; respect for the Creative Common licenses attached to 3D models and the ethical fortitude to not violate those licenses.
