This is a compact and lightweight dual-lock carabiner designed to be fully 3D printable without any metal springs or extra hardware.

The two internal latches provide extra security compared to standard single-latch carabiners, making it perfect for everyday carry (EDC), backpacks, keychains, water bottles, and small gear.

The model is optimized for FDM printing and works well with common materials like PLA, PETG, and ABS.

You can print it in multiple colors for better visibility or style.
