I've been working on a model of my favorite fossil creature, Wiwaxia corrugata. I've had this design successfully made in stainless steel, but this one is in polished WSF. It turned out great. This newer version incorporates more of the features which make it such a cool creature. This design couldn't get made in SS, the spines are likely to break off during handling of the green stage print, but it turned out great in polished WSF. I'm working on a further version which better matches the fossils.
