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.

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.
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.
Create mechanical parts — threads, fasteners, bearings, sprockets, flanges, pipes, and OpenBuilds linear motion parts using bd_warehouse.

|---|---|
analyze_printability | Watertight check, thin wall detection, build volume fit |
analyze_overhangs | Find overhang faces exceeding angle threshold |
suggest_orientation | Test orientations to minimize supports and maximize bed contact |
estimate_print | Filament weight, length, cost estimate by material |
section_view | 2D cross-section SVG to verify internal geometry |
export_drawing | Multi-view technical drawing SVG for documentation |
| Tool | Purpose |
|---|---|
shrinkage_compensation | Scale model to compensate for material shrinkage |
split_model_by_color | Split into separate STLs for multi-color printing (Bambu AMS) |
pack_models | Arrange multiple models on one build plate with padding |
convert_format | Convert between STL, STEP, 3MF, BREP formats |
| Material | Density | Shrinkage | Notes |
|---|---|---|---|
| PLA | 1.24 g/cm3 | 0.3% | Best for most prints, easiest to print |
| PETG | 1.27 g/cm3 | 0.4% | Food-safe option, more flexible than PLA |
| ABS | 1.04 g/cm3 | 0.7% | Needs enclosure, use shrinkage_compensation |
| ASA | 1.07 g/cm3 | 0.5% | Outdoor UV-resistant alternative to ABS |
| TPU | 1.21 g/cm3 | 0.5% | Flexible, good for gaskets and grips |
| Nylon | 1.14 g/cm3 | 1.5% | Strong but high shrinkage, always compensate |
