Scale, rotate, center on the bed, check manifold edges, or fit a printer bed in the same modeling toolbox — agents compose these; humans use this page for the format swap.

MCP / related: dxf_parse, dxf_extents, and gcode_stats are toolbox one-liners — not extra website URLs.

Use in ChatGPT, Claude, Grok, or other AI tools

Add stl_convert_format to a modeling toolbox. Agents pass uploadSessionId, mediaKey, or stl_url plus format ascii|binary — 1 local credit. Not a public /mcp/stl-convert plane.
