Center of the Labyrinth of Chartres (of which I made a 3D design too but haven't printed it out yet).

Also inspired by this cute little egg/chicken/rabbit thingy which I found here under the link: http://www.thingiverse.com/thing:273623

Used a picture of the labyrinth of Chartres that I could place on the bottom of a 3D 'room' in 3D Gamestudio and sculpted it over with some geometric forms. Then made several parts into groups, exported them as a prefab/3DS and finally STL file. Will probably also be able to print out the whole labyrinth within short......
