The prompt
Separate external gear part: 23 mm tip outside diameter, 22 mm through bore, 360 outward-facing fine teeth, 2 mm face width. Fine trapezoidal tooth approximation for CAD layout; verify involute profile and manufacturing tolerances before functional meshing.
Parameters
| Name | Value | Range |
|---|---|---|
| Tooth tip outside diameter | 23 mm | 22.8 – 23 |
| Through bore diameter | 22 mm | 21.5 – 22 |
