parametric 3D generators

What you can build

Why it's different

• Free + open access: No login, no email-wall, no upsell. Donation-supported.
• Parametric, not template-based: Each generator is real code with adjustable parameters — you control width, wall thickness, decoration, text, etc.
• STL + 3MF out of the box: Direct printer-ready exports.
• 594 generators and growing: Curated, each with 6+ presets to give you fast starting points.
• No backend: Everything runs in your browser. No data uploaded.
• Mobile-friendly: Touch-optimized, works on phones and tablets.
