Comet 67P

thingiverse

This is a 3D model of Comet 67P (67P/Churyumov-Gerasimenko) based on data captured by the Rosetta spacecraft and published here by the European Space Agency: https://imagearchives.esac.esa.int/index.php?/page/navcam_3d_models. Three basic variations are provided: * One "as-is" STL that you can modify as desired * One with tree supports generated by Meshmix; scaling this model may introduce issues with support integrity, but it fits on a printer with decent build volume (mine is 235x235 base plate) * One split in half for very easy printing; just use CA or epoxy glue to join the two halves. A fun thing to do is to make/print something to the same scale and put it alongside for comparison. For example, I've printed a scale picture of the Sydney Harbour Bridge. The comet is approximately 4.1km long, so use that as the basis for calculations.
