The prompt
"Please correct the 3D model entirely based on the reference drawing and correct these structural errors:Main Body (Hub): Create a solid cylindrical hub with an outer diameter of $\emptyset 60$ mm and a total length (width) of 40 mm along the central axis.Central Bore: Through the center of the hub, make a $\emptyset 30$ mm through-hole along the entire 40 mm length.Gear Section: On the outer diameter of the hub, there is a toothed gear ring. The outer diameter over the teeth is $\emptyset 80$ mm, and the width (thickness) of this gear section is 15 mm, positioned symmetrically or according to the drawing dimensions. It must have exactly 10 properly formed teeth around the perimeter (not protruding incorrectly inward).Cross-drilled Hole: Through the cylindrical hub wall, make a perpendicular cross-hole of $\emptyset 8$ mm passing through.End Face Details: One of the flat end faces of the hub features a stepped collar or countersunk/conical transition feature leading to the central bore as specified in the technical drawing."
