The prompt
Modify the current part while keeping all internal holes, keyways, bores, and internal features strictly unchanged. Modify only the outer perimeter of the part to transform it into a sprocket/chain wheel specifically designed to fit a link chain with an 18 mm pitch and a 6 mm pin/link diameter (Ø6x18). Ensure the outer tooth profile correctly matches the 18 mm pitch geometry while maintaining sufficient structural wall thickness between the internal features and the new external profile.
