The single zip file includes twelve parts in three formats (.stp, .iges, and .x_t). The CAD of each component of the geometry is released independently with no common assembly. Some images below show the 12 individual parts, seen in gray. Some assemblies are presented in color, though these assemblies are not included in the CAD release.
