I printed this three times with about a six inch diameter.  I was happy with the results.  The sliver color is spray paint.  My first attempt got stuck during printing and I made it into a fridge magnet.  The first image is the first sucessful try.  The final and most sucessful attempt was given as a gift to a friend of the lab who studies this molecule.
