Models are given in Stanford Triangle Format (PLY) and Alias Waveform Format (OBJ) - you can use MeshLab or any other tool to convert them to other formats.

Please note that the models are in planetocentric coordinate system, with Z axis passing through north pole. Actual rotational axis may differ from planetocentric poles, especially for small irregular bodies.
