Mechanical Haptic Heart Design (SG90 Micro Servo)

I am looking for a CAD/Product Designer to engineer an internal housing and mechanism for a small, functional haptic prototype. I am using a standard micro servo (SG90) as the power source.

Requirements:
The goal is to convert the rotational movement of a 360° SG90 servo into a strong, simultaneous physical pulse on both the left and right sides.

The closed enclosure must form a stylized, emoji-like heart shape with a rounded bottom. like the example.
And all parts must be optimized for 3D printing. So think of making it in parts instead of 1 piece
