I just finished my Master Chief Pepakura, and even though I won't be actually finishing it to look realistic (I used regular letter paper, so its really flimsy), I was thinking of how you would install the visor when getting to that step. I have not seen a tutorial on installing the visor on a pepakura model. I haven't glued the paper visor part on because I did not know how you would be able to see while wearing the helmet.
If anyone has a tutorial, or a solution, that would be great.
