The prompt
Create an editable 3D model of a standard metric involute spur gear with the following dimensions: * Number of teeth: 20 * Module: 2 mm * Pressure angle: 20° * Face width: 24 mm * Bore diameter: specify as a separate adjustable parameter * Pitch diameter: 40 mm * Outside diameter: 44 mm * Root diameter: approximately 35 mm Use an accurate involute tooth profile, not triangular teeth. Keep the dimensions editable and generate a valid solid CAD model. Allow rotation, zooming, and measurement. Export the model as STEP and STL files for use in CAD software and an educational creep-feed grinding simulator.
Parameters
| Name | Value | Range |
|---|---|---|
| Module | 2 mm | 0.5 – 8 |
| Number of Teeth | 20 | 8 – 120 |
| Pressure Angle | 20 deg | 14.5 – 25 |
| Face Width | 24 mm | 1 – 80 |
| Bore Diameter | 6 mm | 1 – 20 |
Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
