Parametric Regular Polyhedron Generator (STEP, Customizable, CNC & 3D Printing) · 模型 135267
This is a parametric regular polyhedron model generated using an automated CAD system. Unlike fixed models, this shape is not a one-off design — it can be regenerated with different parameters. Specifications of this model: Shape: [X] (tetrahedron, hexahedron / cube, octahedron, dodecahedron, icosahedron) Edge length: [X] mm (0.1–300) Faces: All congruent regular polygons, all vertices identical Standard: Based on the mathematical definition of the Platonic solids Use cases: Math and geometry teaching models Dice blanks and game pieces Reference solids for CAD and CAE practice 3D printing Mechanical design prototyping ⚙️ Generate your own regular polyhedron (any parameters): https://meta-matic. com/en/3d/regular-polyhedron/ You can freely adjust: Shape (tetrahedron, hexahedron / cube, octahedron, dodecahedron, icosahedron) Edge length and instantly download a STEP file. Why this matters: Most models here are static. This system allows you to generate exactly what you need. Note: The input dimension is the edge length, not the circumscribed or inscribed diameter, so the overall size differs from shape to shape at the same setting. Vertices are built from closed coordinates using the golden ratio and the faces are found as the supporting planes of the convex hull, so no hard-coded face table is involved and every face normal points outward. The solid is sewn from flat faces without any Boolean operation, and each model is checked against independently derived surface area and volume formulas as well as the Euler characteristic.
