Caffeine - Space Filling Model

This is a space-filling model of a caffeine molecule, at a scale of 1 cm per angstrom, or 100,000,000 to 1. Each atom has been split into a separate object, and are joined with small connectors. These are polygonal to assist in orientation (pentagons for carbon-hydrogen, hexagons for carbon-carbon, heptagons for carbon-nitrogen, and octagons for carbon-oxygen). Where two atoms are bonded to each other, they are marked with letters A through Y to assist in assembly as each interface is slightly different. I glued mine together with ethyl acetate, but you can probably use the adhesive of your choice. Total print weight is 80.81 g (8.24 g red, for oxygen; 11.42 g blue, for nitrogen; 17.19 g white, for hydrogen; and 43.96 g black, for carbon). Red, blue, and white can be printed on one 256x256 mm place if printed by object rather than by layer. Black is on a second plate. Total print time is 7 h, 43 min at 0.08 mm layer height.
