The prompt
Create one precision mechanical CAD part in millimeters. The part is a thin closed cylindrical stainless-steel ring. MAIN CYLINDER: - Outer diameter: 40.0 mm - Inner diameter: 38.8 mm - Wall thickness: 0.6 mm - Axial height: 8.3 mm - Perfectly circular and completely closed through 360 degrees - Open at the bottom - No bottom plate TOP FLANGE: - At the top edge of the cylinder, create one continuous horizontal annular flange extending radially outward. - Flange outer diameter: 44.0 mm - Flange inner diameter: 38.8 mm - Flange thickness: 0.6 mm - The flange must be completely circular. BOTTOM TABS: Create exactly two identical rectangular tabs at the bottom rim of the cylinder. - Tabs are 180 degrees apart. - Each tab is 6.0 mm wide circumferentially. - Each tab extends 2.0 mm radially inward toward the central axis. - Each tab starts directly from the bottom circular rim, not from a position higher on the inner wall. - No cylinder wall exists below the root of either tab. - Bend each tab inward and slightly downward. - The free tip must be lower than the root by a 7 degree downward angle. - The tabs must point toward the central axis. - No part of either tab may extend outside the 40.0 mm cylinder outer diameter. - Each tab is one flat straight paddle with only one bend at its root. IMPORTANT GEOMETRY: The cylinder remains a continuous closed ring. Do not create any radial split, seam, slot, or opening in the cylindrical wall. Do not add any other components. This model is for geometric concept verification, not manufacturing drawings.
