Ooooh... I'll be following this project closely :)
It sounds like it could be fun to participate, but I don't have much in terms of funds (or time), so we'll have to see :)
I'm a Curator for @steemmakers, a Maker-centric project here on Steem, so if you/the project make some good posts on creating the marines, feel free to tag us so we can check it out :)
Thanks for your support @pbock, I may need your services in creating somethings. If I designed an insignia, could you create it into a metallic object?
Well. I don't have the equipment to make the metal insignia, but I could certainly make a 3D printable model and then a service like ShapeWays could make it in metal.
You can also check with @markos86, he recently made a casted a Steemit plaque for himself, so he's certainly got the experience for it.
