The famed museum recently posted an updated 3D scan of its complete Triceratops horridus, ready for makers who prefer fossil-grade accuracy over cartoon dinosaurs. Print it for the classroom, your desk, or an ill-advised full-scale hallway display — just bring plenty of filament. The scan is part of the Smithsonian’s effort to digitize more than 155 million artifacts and specimens available in OBJ format for free at Smithsonian 3D Digitization.
