Multi-Twist Möbius Bands

Möbius strips with 1, 3, 5, and 7 twists. These .stl files were exported straight from Mathematica, and then run though Netfabb to repair a few defects in the mesh . Sometimes shapes like the Möbius can have problems with their normal orientation, but I think these are ok for printing. They check out as "orientable" in Netfabb's analysis anyway. I've printed them all without problems.

Here is the Mathematica code I used, for those who are interested in such things...
