Marble Cage v2

Awesome render! If this hasn't been unvalidated when I place my next order, I will buy one in robust.

Happy that you like it. I successfully printed my Cubosphere (http://www.shapeways.com/model/19646/cubosphere.html) with clearances of 0.5 mm. So, if you want to minimize the risks, I would suggest Transparent Detail instead of Grey Robust (for just some tens of cents more).
