Isn't copying someone else's design by digitizing it and the cutting it out on a CNC machine the same thing everyone cry's foul over when people do it with other parts? I can't say how many açusations I've seen whee someone's part looks similar to another person's parts or where they we're blatantly copied. And everyone seems to agree if it was copied, it isn't right and nobody should buy them. What makes copying a prop different?
