I think that this does bring up some interesting issues within the 3d printing industry. As people and those making prints are getting good enough quality and designs to begin selling to consumers, it would appear that the issues of copywriting haven't exactly been worked out. When journalism sites try to pass of someone else's articles or writings as their own, there are enough appropriate measures in place to deter this sort of behavior. The same goes with logo work. If you attempt to use someone else's logo as your own, there are systems in place to help mitigate the risk and deter others from attempting the same in the future. Hosts can issue takedown requests and what not. How are these things handled in regards to 3d printing.

It may even be that it is a matter of awareness for hosts, search engines, online shopping stores, etc... that 3d printing files can just as easily be stolen, printed, and sold as a logo or someone else's article. While it sucks that someone is doing this right now, it could end up being a good thing in the long run. Heck, there is already some other website that is offering ways of protecting an individuals 3d print creations.
