This is a rather unusual model. It's constructed from three overlapping curves built using sines and cosines. However, the curves cross along only two of the axes. The result is that the model is very flexible along the remaining axis and can be pulled out and stretched like a spring. The WSF material gives a surprisingly flexible result, as can be seen in the photographs.
There's no particular purpose to the print. It was just interesting to try.
