Coinfinity – Intelligent Storage for Precious Metal Collectors

Welcome to Coinfinity, a Gridfinity-inspired modular system designed specifically for collectors of gold, silver, platinum, and palladium. Our 3D printable designs offer smart, customizable storage for coins, slabs, assay cards, and more.

🔒 Organize with Precision
From capsule stackers to slab trays, our modules are engineered for perfect fit and functional layout—ideal for safes, shelves, or display drawers.

📱 Tap to Identify
Many of our designs integrate NFC chip support, enabling you to scan a tube or tray and instantly identify, verify, and catalog your collection with our Coinfinity Tracker app.

🧲 Stack & Lock
Magnetic stacking and twist-lock features make organizing and expanding your collection easy and satisfying. Sort by type, size, or metal—your system, your way.

💡 Open Source. Community Driven.
We’re building an open Coin Library and welcome contributions from fellow collectors to help expand support for global coin sizes.

📦 All files include print-ready STL models, README instructions, and personal-use licenses. Commercial licensing available separately.
