User GhostMinnion on the RPF forums is 3D printing a pretty damn good recreation of the fallout New Vegas brotherhood helmet. Even though he’s got the lulzbot taz (same one I do!), he doesn’t quite have the space to print the whole thing at once. Well, maaaybe he could but really it is smarter to break it into pieces anyway.
I understand he used the game model as a base, so it should be pretty dimensionally accurate. Looking forward to seeing the rest of his build come together!
You can find the forum thread here to see his progress pics.
