Based on SOC occupation classification
Design a 3D-printable CAD model using build123d. Use when the user wants to create, design, or model a 3D object for printing.
Modify, transform, or combine 3D models — shell, split, add text, threaded holes, boolean operations, transforms, imports, and 2D views. Use when the user wants to change, combine, hollow, cut, engrave, or visualize an existing model.
Create parametric mechanical components — enclosures, gears, snap-fits, hinges, dovetails, and labels. Use when the user wants to generate a ready-made functional component with configurable dimensions.
Prepare a 3D model for printing — analyze printability, suggest orientation, estimate print time and filament, pack build plates, and export. Use when the user wants to prepare, check, or optimize a model for 3D printing.
Publish or share a 3D model — upload to GitHub Releases, Thingiverse, MyMiniFactory, Cults3D, or search for existing models. Use when the user wants to share, publish, or find 3D models.

measure_model to verify dimensionsanalyze_printability to check FDM suitabilitycombine_models to integrate with other parts if neededthread_type="iso"): Standard metric bolts/nuts. Specify major_diameter and pitch.thread_type="acme"): Power screws, vises, lead screws. Specify size (e.g. "3/8").thread_type="metric_trapezoidal"): Metric lead screws. Specify size (e.g. "10x2").thread_type="plastic_bottle"): ASTM D2911 bottle caps. Specify size (e.g. "L38SP400"). Use manufacturing_compensation=0.2 for FDM.Common sizes: M2, M2.5, M3, M4, M5, M6, M8, M10. Format: "M3-0.5" (diameter-pitch).
simple=True (default): Fast generation without thread detail — good for fit-checks and assembliessimple=False: Full thread geometry — use for final prints or when thread detail mattersmanufacturing_compensation=0.2 for better FDM fit on bottle threadssimple=True for assembly visualization, simple=False for printable threadscombine_models subtractexternal=False for female/internal threads (nut bores, threaded holes)
