a prop helmet i just completed for my brothers birthday. the basic shape came from the airsoft mask i made last summer. it was sanded and filled and cut to become the Kroenen stlyle helmet, the lower mouthparts are the lid of a Lego Bionicle box and the back of a computer mouse. the interior is faux leather. the resin greeble bits are leftovers from my Pit Bot and a few new cast pieces.
