1. Type or copy the HyperFun model: toruscut.hf
2. Render the model with the bounding box x:[0,6], y:[0,6], z:[0,1.2]
3. Generate an STL file with the grid 100 or higher
4. Fabricate the model using Modela MDX milling machine (see two photos of a wooden cut torus above).
5. Material: wood or modelling wax
