I was talking with him yesterday, but he told me it's a huge no-no due to possible copyright infringement and he doesn't want to get into trouble.
Besides, I think he downloaded the print files somewhere, another user here said the files are on Thingverse. Not sure if it's the exact same one, though.
He's just doing it for himself (and for me, cause I really want one).
We were also discussing about which colors should be used, some suggestion input would be greatly appreciated!
In the game, it looks like it's all kind of a grey with a tiny bit of green in it, but I've seen some artwork actually using a slightly blue-ish hue to the grey. And then there are others who have done just normal grey.
