Mechgear

Create and inspect parametric 3D gear models in a browser-based editor with direct export options.

What this tool does

Mechgear generates 3D gear geometry and displays it in an interactive Three.js viewport. You can create a gear, select it, adjust its parameters, transform it, and export the model for use in another 3D workflow.

Who this is for

• Makers prototyping gear shapes and mechanical concepts
• Students learning how parametric geometry affects a 3D model
• Designers who need a quick browser-based starting point for a gear asset

How to use this tool

1. Use the creation controls to set tooth count, diametral pitch, face width, bore diameter, tooth taper, and color
2. Create a gear and inspect it with orbit controls in the 3D viewport
3. Select a gear to edit its parameters or use transform controls to reposition it
4. Export the selected model or scene in the available GLB, STL, or OBJ formats

Inputs

Inputs include gear geometry values such as number of teeth, diametral pitch, face width, bore diameter, tooth taper, and color. The editor also accepts viewport selection and transform interactions.

Outputs

The output is an interactive 3D gear model that can be viewed, selected, transformed, and exported as GLB, STL, or OBJ for downstream inspection or editing.

Example use cases

• Compare how tooth count and pitch change a gear’s proportions
• Build a rough gear asset for a visualization or 3D-printing workflow
• Test placement and orientation before moving a model into desktop CAD software

Limitations

This is a browser-based geometry generator, not a mechanical engineering validation tool. Exported gears should be checked in CAD and tested for fit, strength, tolerances, and manufacturing requirements before use in hardware.
