The prompt
Modify only the Cat Rotor component. Redesign the cat as a cute, recognizable cat lying down and curled naturally around the central spinner hole, creating an organic circular composition. The cat's body, paws, head, and curled tail should form the overall silhouette. Keep the central mounting hole EXACTLY the same diameter, position, depth, and geometry as the original. Do not modify the hole or any mechanical dimensions. Preserve the original rotor's overall size, thickness, and 3D-printable solid geometry. Use simple, smooth shapes with minimal details, suitable for FDM 3D printing. Do not modify any other component.
