Here we have another 3d model that can only be 3d printed with a chimera hot end. As you can see there are 2 colors involved and are not layered. it is about 1/10th actual size and was 3d printed in about 11 hours with the chimera hot end doing its thing. we could 3d print a life size helmet if you would like us to. just remember 1/10 so it would be a few dollars more for life size.
