The prompt
Refine the current model into a real robotic pitch joint. Keep the RDS3115MG housing and coaxial dual-shaft axis. Add a circular replaceable forearm output hub on one servo shaft, centered exactly on the pitch axis. Add a matching structural support on the opposite shaft. The output hub must rotate with the servo while the main housing stays fixed. Add strong side plates and gussets connecting the housing to the fixed robot structure. No bearings or separate axle. Keep the servo removable. Maintain 4 mm walls and 6 mm high-load areas. Make the output hub and mounting dimensions editable.
