Mesh9 atom spheres + 9 bond cylinders, each a closed outward-oriented solid; the solids intersect by design.
Atomic radiivan der Waals radii, Bondi 1964 (doi:10.1021/j100785a001). Sphere scale and bond radius are presentation parameters, not chemical quantities.

The STL format carries neither bond order nor colour. Aromatic and single bonds are rendered as identical cylinders; bond orders are preserved in this record and in the accompanying metadata, not in the mesh.
