I wonder if he took his grooved cylinder design from the Cobray Pocket Pal[1] or the earlier Mauser C78 “Zig Zag” revolver[2]. He's definitely wrong about it being the "first functional 3D-printed repeating firearm that has been printed using a consumer 3D printer", though. In May 2014, a Japanese man made a pepperbox revolver[3], and an even earlier metal-lined-barrel pepperbox revolver was built in September 2013 [4].
