I made a post a while ago on how I made the visor for my MK6. If you're looking to go the good ol' vacuum formed plastic route, it might give you a tip or two. 1st Build - MJOLNIR MK VI Master Chief Armour (Halo 3)Looking for a visor for my 3D printed Noble 6 helmet. Can someone assist?
I basically did the same thing mentioned in this thread. Vacuum forming, dye, and chrome.
