Sony PS-LX500: Spare Parts - Drive?


We'r searching technical details for two components from the tonearm drive of the Sony PS-LX500: the worm gear and the main gear. Specifically, I am interested in knowing if anyone knows of any shops that carry these parts? Or if anyone has technical drawings, exact dimensions, or ready-to-use CAD/STL files, we would fire up the 3D printer. Thanks in advance for any tips!
