I will get a 3d file today and start unfolding. When unfolding done i will start to build it. As I saw so far, people made some helmets of mark 45 (including me). 3d printed some parts. But a complete pepakura file hasn't been published yet.
Many people around here (including the usual 3D modelers) bought a 3D printable version for a decent sum of cash and do not have the rights to covert it to 3D, provide it for free, or sell it. So I can't see a foam version coming in the remotely near future.
