Public Library

Welcome to GrandpaCAD – a growing library of AI-generated 3D models you can download, customize, and print at home. Whether you’re a beginner experimenting with AI CAD tools or a maker looking for fresh design ideas, this collection is here to inspire you.

What Are Procedural AI 3D Models?

Procedural models are designs created with algorithms and AI. Instead of sculpting by hand, the computer generates shapes based on prompts. And this is exactly what we made with GrandpaCAD.

Why Use AI for 3D Printing?

• Faster design process – generate models in minutes
• Customizable – tweak dimensions, patterns, or shapes
• Unique results – no two models look the same
• Learning tool – see how AI interprets geometry

Free 3D Model Library

Each model can be easily changed by prompting the AI to do so. Simply select the model, then "Remix" and finally describe how you want to change it and AI will do the rest.
