I've designed this Porpoise with Clayoo in Rhino 5 - it's a lovely tiny Whale in the North Sea.
Converted to STL and printed with my Ultimaker 3. The Material used was ABS. Printing with this is a little bit tricky but gives verry good results when grinded and polished. Finally cast in brass.
After finishing this will be a door lever handle for our small and charming home.
