## What is stl?

stl-er is the world's first AI-powered 3D model generator built for 3D printing.

Simply describe any object in plain text — and get a fully parametric, functional 3D model in seconds. No CAD experience needed.

HOW IT WORKS
1. Describe what you want (e.g., "phone stand with cable slot")
2. AI generates a precise 3D model using CAD
3. Adjust dimensions with live parameter sliders
4. Download the STL file — ready for your 3D printer

KEY FEATURES
• AI-Powered Generation — From text prompt to 3D model in seconds
• Live Parameter Sliders — Fine-tune dimensions, rounding, and details in real-time
• AI Refinement — Modify designs with follow-up prompts ("make it taller", "add ventilation holes")
• Instant STL Downloads — Export files ready for any 3D printer or slicer
• 3D Preview — Rotate and inspect your model before downloading
• Community Library — Browse, remix, and share models created by other makers
• Cross-Platform — Seamlessly sync between iPhone, iPad, and Web

PERFECT FOR
• 3D printing enthusiasts and makers
• DIY builders and hobbyists
• Product designers and engineers
• Educators and students
• Anyone who wants custom 3D models without learning CAD software

WHY stl-er?
Traditional CAD software has a steep learning curve. AI model generators produce meshes that aren't optimized for printing. stl-er combines the precision of parametric CAD with the simplicity of natural language — every model is mathematically exact, fully customizable, and ready to print.

Every design is solid, manifold, and slicer-ready.

Start creating. Now.
