EnclosureAI 🚀

The future of parametric enclosure design. Describe your device. Get your STL. Get printing.

EnclosureAI converts natural language into production-ready 3D printable enclosures using Llama 3.3 and OpenSCAD.

✨ Features

• Prompt-to-CAD: Natural language interpretation of mechanical requirements.
• Iterative Chain: Design through conversation—stable versioning across prompts.
• Interactive 3D Preview: Full Three.js viewer with diagnostic wireframe & transparency modes.
• Engineering Accuracy: Auto-calculated clearances, PCB standoffs, and lid tolerances.
• Pro Export: Export and download both .stl (printing) and .scad (manual editing).
• Free Trial: 5 free generations for new users via Firebase tracking.

� Quick Start (Local Setup)

1. Prerequisites

• Node.js v18+
• OpenSCAD installed and added to system PATH.

2. Backend Config

• Navigate to /server
• npm install
• Add your GROQ_API_KEY to .env.
• node index.js (Server runs on port 5000).

3. Frontend Config

• Navigate to /client
• npm install
• npm run dev (Frontend runs on port 5173).

🏗️ Architecture

1. Input: User signs in via Google and submits a prompt.
2. Reasoning: AI interprets the description into a Parametric Design Specification (JSON).
3. Generation: cadGenerator.js converts JSON to a modular, variables-based OpenSCAD script.
4. Compilation: OpenSCAD CLI compiles the script into a binary STL file.
5. Preview: Three.js renders the STL on a GPU-accelerated canvas for inspection.
6. Download: User downloads assets directly from the workspace.
