To be honest, the file was useless, the printed helmet isn't wearable, there is no way to connect the pieces together unless you want to "weld" them using some cheap soldering tool and smell some fumes. No solution for visibility. And the whole thing isn't true to original design, the nose part isn't supposed to be smooth, it's angled on every image. The shape of the helmet isn't true to original design as well. "Costume Made" in the name shouldn't be present, the only possible purpose of this one is maybe for display? But in the end, it doesn't have that authentic look all Ruiner fans liked.
