We have developed an open-source 3D printed soft robotic prosthetic hand with multi-functional capability addressing the gap between existing designs and the practical requirements.
More details are provided in the following open-access paper in PLoS ONE:

Main characteristics of the X-Limb design:
- Overall weight: 253gr
- Grasp types: Three grasps types (power, pinch, and tripod) with capability of individual finger movement
- Grip force: Power grasp force of 21.5N and pinch grasp force of 10.2N
- Hand closing/opening speed: 1.3sec
- Cost: Bill of material cost of 200 USD (excluding quick disconnect wrist but without factoring in the cost reduction through mass production).
