Milnor fibre of the cusp.

thingiverse

The Milnor fiber depicts a simple cusp singularity's boundary as a trefoil knot. To calculate this, Sage can be used for equation computations by combining stereographic projection with singularity definitions, separating real and imaginary parts. Post-processing involves using Meshlab to generate meshes and Blender for mesh thickening, while trimming the part corresponding to the opposite fiber.
