Generate 3D-printable ornaments in Python: torus knots and golden-angle petals

Using Python and manifold3d, users can generate unique 3D-printable ornaments. Penrose tiling is created via Robinson triangle subdivision, starting with ten triangles split by the golden ratio to achieve fivefold symmetry. Additionally, torus knots are produced by sampling curves and unioning convex hulls of sphere pairs, creating smooth tubes without sweep tools. These methods allow for the creation of watertight meshes, including aperiodic ornaments and complex knots, which can be sliced directly for printing.
