Is... is that six regular paintball guns mashed together to make a gatling?
I love some of the set pieces you've got on the Instagram page- helmets, case of paint, markers... And Roger's armor and texturing looks great!
Now, I have to ask- what would it take to convert one of those models into a format that could then be imported into a 3D printer? A buddy of mine just picked up a Prusa, and showed me a few test prints. It'd be way cool to print a physical model of these guys.
