the wheel of rubber molecule

My Molecule is the molecule of rubber. Its actual name is polypropylene. In the 3-D design I made the molecule in the shape of a wheel. I chose a wheel because a wheel is one of the most common things made with rubber. The materials of the molecule are six Carbons, three Hydrogen, six Methylenes (CH2) and three methyl groups. The blue is Carbon, the red is Methylene, the orange is a methyl group and the pink is Hydrogen.
