Cog Hoplite Shield

Ever encountered a unit of robot hoplites, but they don't have the round shields of a proper hoplite? I have! And it was driving me crazy-- especially when the idea of the cog's teeth interlocking to form a phalanx is RIGHT THERE. Completely amateur work, on a free software, but I'm pretty proud of how it turned out.If nothing else, hopefully if someone has the same idea I did they won't have to settle or figure out how to 3D model just to get what they want.Cheers! I will be printing this out at 25mm, and ~1mm thickness, to be equipped by a 28mm model. Will post pictures when I get it all figured out myself.   P.S. I cut a 2mm notch into the back of the shield that should fit an arm so it's easier to glue together. For some reason I was unable to upload an image of the back, but I will try again when I need to add the photos of the real-life print results.
