3d-printed model of the WW1-vintage Russian Garford-Putilov armoured truck, based on the chassis of the American chain-driven Garford lorry. It served throughout the First World War and after, used both by the Soviets and organisations like the Freikorps. Apparently the Germans even encountered some outside Leningrad (?) in WW2, though they didn't last long.
It really needs to be printed in FUD, because in WSF it's lost most of its rivets, and rivets are unequivocally good.
