Multi-Function attachment for a prosthetic arm

The attachment is design keeping in mind ADL ( Activities of Daily Living ). A person would need to hold different object while performing these tasks. A single attachment would either be costly(Technology Investment) or unable to fulfill the needs. An good example would be to perform all tasks in a kitchen. A person can have one attachment specifically for that and multiple sub-attachments to support it. Prototyping : Could be 3D printed or made of wood.
