Model created in Zbrush. It is watertight and ready for printing/milling. It was created with molding and casting in mind.

Inlcudes a 4 Mil polygon, quad topology OBJ and a decimated, 1 Mil STL.

Nominal size (although easily adjustable in any 3D software) is:width: 56.23 mm height: 100 mm depth: 37.24 mm volume: 41,68 cm3

For hollowing models I can recommend Meshmixer as an easy and free option.
