Actually Mars! A fresh (in the mars sense of the word) ~1km-diameter impact crater on the Arcadia Plantia. Data and details available at http://www.uahirise.org/dtm/dtm.php?ID=ESP_025735_2185. This model is at 1:1,000,000 scale, with a 20x exaggeration in height. Only 1mm thick, this is meant (and hoped) to be printed in full-color plastic.
