Mare Orientale imaged using a new prototyper that prints in plastic. Lit from behind, you can just see the multi-rings that form the basin. About 4 inches across and 2mm thick. LOLA data, shell generated in Mathematica, shell thickened with GeoMagic Studio. https://finkh.wordpress.com/2011/04/01/mare-orientale/ has some snapshots of the data.
