A different Stefan (2×4) than the guy who built the Sunblade below has built the great maker. He’s captured the feel of the sandworms from the old Dune movie perfectly. The three-way split mouth filled with teeth is absolutely perfect. Also note the micro shuttle (there are no wings, so it can’t be an ornithopter) for scale.
While you’re in Stefan’s gallery, make sure to check out his light-cycles too.
