When the court system decides that Samsung can't make a phone that looks sort of like an iPhone, it's a good bet that courts will find that it's illegal to print, or assist printing of, a replica of some $megacorp object or part.

I know a bunch of people printing off models of their characters from the game 'City of Heroes' (incidentally if you ever want to see how not to close a service, check out NC Soft's behaviour over the last couple of weeks) before the doors shut and a lot of them would probably pay a substantial amount for a slightly better quality painted one.
