Iron Man MKV Suitcase

This was originally a pepakura file. It was modeled originally by Dungbettle, i believe. So I am not the creator nor do i take ownership for it. I simply exported the file to obj so i can make it printer ready so i can make it as a carrier for my asus g73jh. But i dont know what im doing with the modeling software. I'd love if someone can help me out to get it ready to print
