Conway Knot

The Conway Knot made news again after Lisa Piccirillo proved it is not slice. https://www.quantamagazine.org/graduate-student-solves-decades-old-conway-knot-problem-20200519/ https://arxiv.org/abs/1808.02923 I decided to make a geometric version of the knot using a triangular lattice. It can be scaled up and used as a trivet if you use ABS or something heat resistant. It prints nicely without support.
