This is a simple klein bottle. It doesn't exactly go all the way around at the top but it still has the characteristics of an actual klein bottle. If you pour a liquid in the top and rotate the bottle, it will eventually end up in what appears to be the walls of the bottle.
I guess this is the kind of Klein bottle you wold drink out of...
The angles are gentle on all 3D printers. No support material required!
I haven't tried this yet, so feedback will be appreciated.
- Skeinforge. Raft recommended. Support material not required.
- Watch as a physically impossible object appears on the orange acrylic plate.
- Put it on your desk as a "desk ornament."
