Chris has some interesting files so I for one are interested/curious to see how this will turn out. It does have some features though that reminds me of old FX armor, approvable but not that accurate. Looking at the helmet I feel hesitant it will look good enough in printed form to be approvable. But hey, you’ll never know and if it’s just a helmet you’ll be needing to complete this project there are plenty options out there. Haven’t heard of anyone trying this before so you might be a pioneer
Good luck!
