This symbolic 3D sculpture portrays a human heart wrapped in heavy chains and locked shut. The piece reflects themes of emotional protection, heartbreak, and the unseen weight many carry inside.

Designed with anatomical structure in mind, the model brings both realism and symbolism together into one dramatic form.

💡 This model has been fully test printed (see photos) and is optimized for FDM printing with minimal supports required, mainly underneath the lower chain curves and padlock.

🖤 Ideal as a gothic décor piece, a gift with emotional meaning, or a dramatic conversation starter on any shelf.
