The prompt
Create a 3D CAD model of a **14-ball-stud drive sprocket for a flexible-track welding carriage**. This is not a conventional toothed gear. **All dimensions in mm:** - Ball-center pitch circle diameter (PCD): 80 - Number of balls: 14, equally spaced over 360° - Ball diameter: 6.35 - Stud diameter: 5 - Effective stud protrusion: 4 - Disc outside diameter: 92 - Disc thickness: 8 - Hub outside diameter: 30 - Total hub length: 20 - Central shaft bore: 12 - Provisional keyway: 4 wide × 2 deep **Track for engagement visualization:** - Width: 60Generation failed: Prompt too long. - Thickness: 2 - Obround slot length: 6.5 - Slot width: 5.5 - Initial slot pitch: 17.95 Create a concentric disc and hub, place 14 identical spherical balls on the 80 mm PCD, and model the studs as separate components if possible. Generate an isometric view, dimensioned front and side views, and an exploded assembly. Check ball-to-slot interference and report any mismatch. Keep all dimensions editable. Mark unverified dimensions as provisional. Do not claim structural safety. Export STEP and a native CAD file if supported.
