This is a 3D-printed earring design composed of multiple concentric heart shapes, arranged one inside another. Each heart is independently rotatable around a common central axis, creating a dynamic, kinetic jewelry effect when worn. The rotation is smooth and intentional, adding movement and visual interest rather than being purely decorative.

At the center of each concentric heart, there is a precisely designed hollow groove or channel. This groove is meant to accommodate a thin string, wire, or filament, which acts as the rotational anchor and assembly element. The string or wire can be inserted in two possible ways:

• During the 3D printing process, by pausing the print at a predefined layer height, placing the wire/string, and then resuming the print so it becomes partially embedded.

• After printing, by threading the wire/string through the aligned grooves of all concentric hearts, allowing controlled rotation while securely holding the structure together.

The overall design balances modern geometry with a soft, emotional motif, making it suitable for lightweight, wearable jewelry. The open grooves also allow for future enhancements, such as inserting metal wires, colored threads, or reflective micro-elements, without altering the core structure.
