About this 3D model

I developed this cross model specifically for sand casting: All the sides are slightly tapered so the mold will be easy to remove from the sand. About 20 minutes modeling (in Maya), 2 hours printing, and 45 minutes casting (10 minutes making the mold, 15 minutes melting the metal, 20 minutes cleanup & paint). In the attached images, the gray version is the print, and the silver/black is the aluminum cast. As printed/cast, it's about 7" long.
