This flaming heart pendant represents passionate love, desire, and an unbreakable emotional bond. Designed as a Valentine’s Day ornament or statement keychain, the heart-and-flame combination creates a bold romantic symbol that prints beautifully with smooth transitions and expressive depth.

Best Material

PLA – Ideal for vibrant Valentine colors, clean flame shapes, and lightweight hanging pieces

Resin – Highly recommended for a premium, high-gloss finish that enhances the flame details and heart curvature

Layer Height

0.16 mm for PLA on Creality K1C (excellent detail with strong structure)

0.05 mm for Resin (ultra-smooth, luxury gift-quality finish)

Supports

Minimal supports required

Light supports may be needed under the upper flame tips and the hanging loop, depending on slicer settings. The heart body prints cleanly without supports.

Orientation

Print upright, with the heart tip facing down and the hanging loop at the top.

This preserves the flame definition and ensures a strong, clean attachment point.
