Create and render OpenSCAD 3D models. Generate preview images from multiple angles, extract customizable parameters, validate syntax, and export STL files for 3D printing platforms like MakerWorld.

OpenSCAD Skill Create, validate, and export OpenSCAD 3D models. Supports parameter customization, visual preview from multiple angles, and STL export for 3D printing platforms like MakerWorld. Prerequisites OpenSCAD must be installed. Install via Homebrew: Tools This skill provides several tools in the tools/ directory: Preview Generation STL Export Parameter Extraction Validation Visual Validation (Required) Always validate your OpenSCAD models visually after creating or modifying them. After writing or editing any OpenSCAD file: 1. Generate multi angle previews using multi preview.sh 2. View each generated image using the read tool 3. Check for issues from multiple perspectives: Front/back: Verify symmetry, features, and proportions Left/right: Check depth and side profiles Top: Ensure top features are correct Isometric: Overall shape validation 4. Iterate if needed : If something looks wrong, fix the code and re validate This catches issues that syntax validation alone cannot detect: Inverted normals or inside out geometry Misaligned features or incorrect boolean operations Proportions that don't match the intended design Missing or floating geometry Z fighting or overlapping surfaces Never deliver an OpenSCAD model without visually confirming it looks correct from multiple angles. Workflow 1. Creating an OpenSCAD Model Write OpenSCAD code with customizable parameters at the top: Parameter comment format: // [min:max] numeric range // [min:step:max] numeric range with step // [opt1, opt2, opt3] dropdown options // Description text plain description 2. Validate the Model 3. Generate Previews Generate preview images to visually validate the model: This creates PNG images from multiple angles. Use the read tool to view them. 4. Export to STL Camera Positions Common camera angles for previews: Isometric : camera=0,0,0,45,0,45,200 Front : camera=0,0,0,90,0,0,200 Top : camera=0,0,0,0,0,0,200 Right : camera=0,0,0,90,0,90,200 Format: x,y,z,rotx,roty,rotz,distance MakerWorld Publishing For MakerWorld, you typically need: 1. STL file(s) exported via export stl.sh 2. Preview images (at least one good isometric view) 3. A description of customizable parameters Consider creating a model.json with metadata: Example: Full Workflow Remember : Never skip the visual validation step. Many issues (wrong dimensions, boolean operation errors, inverted geometry) are only visible when you actually look at the rendered model.
