Here are two wood carvings digitized with 123D-Catch. The hammerhead shark is a souvenir of the Galapagos and the dolphin comes from Belize. The shark is at 80% scale and the dolphin at 60% scale.
There are no flat surfaces on either carving. A corner of each was cut off to make a flat surface for printing. The small flat surfaces should be placed on the build platform and the carvings printed with support.
