You will need to print the following parts: * Three fingertips * Three servo-gear units * Three servo-trumpet attachments * Two servo mounts * One servo mount in the middle * One rack on the right side * One rack on the left side * One rack in the middle Or, you can simply print everything at once using build-plate.stl. # Required Hardware A trumpet is required. Three Micro servos are also needed (I used TowerPro MG90S). Six M3x10 screws for mounting the servos and six M3x30 screws for mounting the mechanism to the trumpet are necessary. Additionally, three M3x16 screws and three M3 nuts are required for attaching fingertips to the fingers.
