An Autodesk ReCap Photo copy of a garish porcelain pig bought at an estate sale. About 1/3 scale. A solid version and a hollow version with closure are provided. The hollow version has an internal space of about 40 cubic centimeters. It will hold 60 pennies, 80 dimes, or 18 ounces (500 grams) of tungsten or gold shot.

The screw threads were constructed with "threads.scad" which is available at http://dkprojects.net/openscad-threads/
