Asteroid models for three bodies, Castalia, Kleopatra and Geographos based on radar and optical data. Model reconstruction is based on digital models developed by Scott Hudson of Washington State University (http://users.tricity.wsu.edu/~hudson/Research/Asteroids/models.html. Note the models are NOT in scale relative to each other (Castalia is 1.8 X .75 km, Geographos 5.1 x 1.8 km, and Kleopatra 217 x 81 km). The stls were sized to give reasonable size models buildable without support structures given their strange shapes.
Files were translated from .obj format to .stls using Rhino3d v4.0 and printed on a Makerbot using white ABS. The clearish discolored areas seen inthe phots are from leaving them a bit too long in acetone (45 seconds) which I did to smooth out some of the threadiness near the base.
