A customizable sphere puzzle. Inspired by the Wikipedia logo. You can put a letter or text on every piece of the sphere. In the customizer you can select from those fonts that are also available in the write.scad thing (http://www.thingiverse.com/thing:16193)
There are some pieces ready for download, but you can use the customizer to create pieces with your own text, or size etc.
Also read the instructions.
Update 2015-03-20: Now my sphere is finished. I've added some more pieces.
