Here is a small wooly sheep.
It was created with 123D Catch from a ceramic garden ornament. The ornament contains reflective additions and is white and shiny - see image. It was dulled with fine chocolate powder to aid 123D Catch.
The orginal sheep is 20 cm wide, 35 cm long, and 30 cm high. Wooly_sheep.stl is 33 mm wide, 57 mm long and 48 mm high, or an approximately 1/6 scale version.
It can be printed directly on the build platform. I used 5% infill and 2 shells and it printed in about 75 minutes. The ears overhang slightly but the print was fine.
