SG90 servo horn

SG90 servo horn: 1 size. Dimensions: faceplate thickness, mount hole diameter, mount hole pitch. Use parts in kernelCAD Studio or MCP.

Front and top view of SG90 single arm horn (community reference), 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('sg90-horn-single-arm');
