Earth Ring
thingiverse
You can print this out in size 12 at Shapeways for yourself, or get creative and produce it on your own. Be sure to check out the thing:363298 program on Thingiverse that masterfully wraps height maps around a sphere - it's written in Processing, not OpenSCAD. Pair these two programs together with the ring sizer (that makes three) and you'll be all set to craft any ring imaginable, far beyond the majestic Earth. Have fun!
