Nice work so far Chris
Looks like you're working past the lack of uniformity between sections, great job. You've definitely got what it takes to make this armor look awesome. Can't wait to see it finished.
I have to agree with Joseph here. From what I can see he has consent to print the files. So long as he doesn't remove the watermark and resell them it shouldn't matter what material they're made from of as a finished product.
Bishop has shown no desire to resell them so it's safe to say they are for his own personal use.
