About this 3D model

Mathematically generated object (thanks MathMod). Can be a pendant, or perhaps just a toy to spin on your desk. Perhaps print 2 small ones for earrings. Maybe a set of 2, 3, or more, on a neck chain is just the thing. You can always print different sizes to make the set look just that bit more interesting. Or even mirror-image so the twist goes in the opposite direction. The gray image is from MeshLab. There is a screenshot of the file loaded into Cura, ready to save after slicing, but this design is likely to be too hard to get a good print out of a desktop filament machine.
