Lucas, first of all thanks for sharing these, I really appreciate what you've done and I will download them later on. Don't worry about them not being perfect, I have seen most of the templates out there and NONE are perfect but you could take the best from each and make your own.
you can get to that line, but be patient, cut a bit, measure, adjust, etc, until you get it right, about the teeth I would recommend small files instead of a dremel
I think Mason is working on the Kashyyyk helmet, on the Legacy part I don't know, maybe someone is working on it secretly :ninja: (maybe even Mason, hahaha)
