Coolguy26 - I do not think the piece comes up when the faceplate goes up too. On my own helmet i will be making it so that the piece you are referring to remains in place while the face plate moves up.
Update - Or should i say downdate? The helmet i printed out, painstakingly cut out, and am now through a good part gluing together...is WAY to big for my head. Why you ask? Apparently i am an idiot. When the print screen asked me if i wanted to adjust the setting or whatever the message was, i clicked no instead of yes. Hence, larger helmet and me kicking, screaming, and crying as i throw the pieces into the trash. ( I promised pictures so here is my failed attempt that i will be tossing into the trash) back to the printer..ill have to have another go at it......F@&%!!!!!!!!!!!!
