Christian Heart Keyring

Elevate your everyday carry with this clean, minimalist Heart & Cross keychain. Specifically designed for multi-color 3D printing, this model features a perfectly recessed cross that creates a sharp, professional contrast against the heart-shaped base.

Forget flimsy, paper-thin prints – this model is 2mm thick, providing a solid, premium feel and the durability needed for a keychain that actually lasts.

Designed for Performance

• AMS Ready: Optimized for the Bambu Lab AMS system. The color transitions are clean and the geometry is specifically tuned for multi-color efficiency.
• Built to Last: With a reinforced 2mm profile, the eyelet is sturdy enough to handle daily wear and tear without snapping.
• Production Friendly: The flat top and bottom surfaces ensure perfect bed adhesion and a factory-like finish.

Recommended Print Settings

To get the best results, I recommend using PLA with the following settings in Bambu Studio:

• Walls: 2 (for extra strength around the ring hole).
• Infill: 15-20% (Gyroid).
• Ironing: Enable "All top surfaces". This is the secret to getting that ultra-smooth, professional look on both the heart and the cross.
• Batch Printing: If you are printing multiple units, fill the build plate! Printing 10 at once is much more efficient with the AMS than printing them one by one.
