This heart-centered flower charm represents sweet love, affection, and joyful romance. Designed as a Valentine’s Day ornament or keychain, its rounded petals and soft heart centerpiece create a charming, playful design ideal for smooth and colorful 3D printing.

Best Material

PLA – Perfect for pastel colors, smooth curves, and lightweight Valentine charms

Resin – Recommended for a premium, glossy finish that enhances the soft petal shapes and heart detail

Layer Height

0.16 mm for PLA on Creality K1C (clean layers with excellent surface quality)

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

Supports

No supports required

All petals, heart shapes, and the hanging loop maintain safe angles and print cleanly without supports.

Orientation

Print upright, with the flower base touching the build plate and the hanging ring at the top.

This preserves petal symmetry and ensures a strong, clean loop for hanging.
