The prompt
Design a wearable mechanical kinetic gear ring as a real, editable parametric CAD assembly. The ring must have: 1. A circular finger band with an 18.5 mm inner diameter and comfortable rounded edges. 2. A compact gear housing mounted on the top of the ring. 3. Two small bevel gears with intersecting axes at 90 degrees, designed to mesh correctly. 4. Two supporting shafts and suitable mounting supports. 5. An open-top housing so the gears remain visible. 6. A compact, symmetrical and aesthetically pleasing design suitable for a wearable ring. Use millimetres. Keep the mechanism small and proportional to the finger ring. Make the gears mechanically functional, not merely decorative. Ensure there is sufficient clearance between all moving components and the finger. Generate separate editable components and assemble them with correct alignment. Provide an exploded view and export the complete assembly as a STEP file compatible with SolidWorks.
