The prompt

Create a 3D CAD model of a Geneva drive driver wheel in millimeters. Outer diameter must be exactly 100 mm, thickness 15 mm. In the exact center, create a through hole with a diameter of 20 mm. On the face of the wheel, near the outer edge, add a cylindrical driving pin with a diameter of 10 mm and height of 15 mm, positioned at a radius of 35 mm from the center. Export as STEP file.Create a 3D CAD model of a 4-slot Geneva mechanism cross (Maltese cross) in millimeters. The overall outer diameter must be strictly under 100 mm (approx 90 mm), thickness 15 mm. In the exact center, create a through hole with a diameter of 20 mm. The cross must feature 4 evenly spaced radial slots designed to fit a 10 mm driving pin, along with proper locking arcs. Export as STEP file.
