Trefoil Knot (Sliced)

This is a trefoil knot sliced in such a way that the inner part can rotate independently on its own axis and completely transforming the shape of the object.

It was inspired by Numberphile's video [Topology of Twisted Torus](https://www.youtube.com/watch?v=3_VydFQmtZ8 "Numberphile, Topology of Twisted Torus")
