About this 3D model

This is a very nice Toy, I have seen it made out of wood for some hundred Euro. You can turn the internal balls but you cant remove them. 19.3.13 I got feedback about my script and will update it 22.03.2013 I updated the script and added 2 more balls. 2015 | printed the Ball in Ball in Ball with my Mendel 90 with support sliced with Slic3r and it is working fine. 50% size
