My girlfriend designed the heat shielding for the new NASA mars rover (the one that just launched). "Curiosity" started its journey on top of an Atlas V launch system, so I picked that as the theme for this week's earring.
Rockets, being volumes of revolution, are easy to model. I altered the scale lines just a bit to help it print better.
Print (a raft will probably help adhesion, but I didn't need one). Drill hole in top of rocket for earring wire. Glue earring wire into hole. Paint. Varnish.
