Coupling Disc with Offset Mounting Holes

Create a high-precision, completely solid, rotationally symmetrical parametric 3D CAD model of a coupling disc. Outside diameter: 44.0 mm. Total thickness: 6.0 mm. The model must feature the following precise cutouts centered on the origin: 1) One central, through-all bore with a diameter of 8.05 mm. 2) Four through-all mounting holes with a diameter of 4.0 mm, arranged symmetrically on a Pitch Circle Diameter (PCD) of exactly 24.0 mm. Crucial requirement: These four holes must be rotated by 30 degrees relative to the magnet pockets, so they sit perfectly centered in the solid gaps between the magnet pockets with absolutely zero geometric overlap or intersection. 3) Six circular pockets (blind holes) for magnets, each with a diameter of 10.2 mm and a depth of 3.2 mm, symmetrically arranged at 60-degree angles to each other on a larger Pitch Circle Diameter (PCD) of exactly 32.0 mm. The magnet pockets must leave a closed solid bottom wall of 2.8 mm on the front side. The body must be 100% solid. Export as a STEP file.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
