Spur gears

Spur gears: 12 sizes. Dimensions: pitch diameter, outer diameter, bore. Use parts in kernelCAD Studio or MCP.

Front and top view of Spur gear module 2, 12 teeth, projected from the catalog STEP file. The catalog solid is simplified (no modeled thread or drive recess), so read dimensions from the table, not from the drawing.

Use a size in a model

Every size is a catalog part with a STEP solid and mate connectors. Use a code-CAD script, or ask an agent through the MCP fetch_part tool, by its part ID:

const part = await lib.fetchPart('spur-gear-m1-z12');
