Stereographic projection maze

When I first saw the amazing [Stereographic projection](http://www.thingiverse.com/thing:202774), one of the challenges I setup is doing the stereographic projection with a self-generating maze. From then on, a year has passed and it's finally completed.

The customizer will generate a different maze every time you run it. You may input different values for the `maze_rows` parameter. The sphere radius would be `block_width * maze_rows / 6`. W
