I cast these bears from a 3D print. Calit2’s Drone Lab was nice enough to give me the model. The reclining bear was a mistake, but he’s turned out to be my favorite. Cast in smooth-on 360. The first is before polishing, the 2nd is after (took me days). They’re still full of tiny bubbles, and will be until I buy a “degassing chamber”.
Stop by the lab if you’re interested in doing something like this yourself.
