I think this is the smallest I can possibly make the Earring RBS given shapeways minimum wall thickness limitations for white strong and flexible. The frame is 1mm and the rails are 0.8 mm. Yes, I know 0.7 is real minimum but I don't want to risk it. Again, I haven't printed and tested it yet so I'm not sure if it works, but it should. It is very small at 1 inch wide by 2.25 inches tall. There is a loop at the top for hooking to an earring or it will also stand on its own. A very unique earring! Don't forget that if you want it for an earring you need to purchase two (one for each ear). You'll notice that this one is a little smaller than the earring rbs I uploaded previously. To play with it, you'll need to detach the attached 5 marbles. http://www.youtube.com/watch?v=-as24TSv2-U
