Klein Bottle (Q53376)

After the previous attempt at making a Klein Bottle that actually looked okay (see http://www.thingiverse.com/thing:12359) , I present to you: Yet another Klein Bottle! What's so special about this one? Well, no modeling at all was done on it (the shape comes directly from the Mathworld article (http://mathworld.wolfram.com/KleinBottle.html)) and it's still printable! Disclaimers: There's a slight ridge around the edge of the bottle, as well as a ridge around the nozzle. Both are defects of the widening algorithm I used. Additionally, it's not quite nonsupportable, there's still a small bridge at the top which will require some filing. Lastly, do not drink from klein bottle. It doesn't actually taste that good and it isn't waterproof.
