Gripper

grabcad

To create this model, I started with the base as the fixed part. Then, I did concentric mates with the arms, attaching them together with the base. Next, I attached the grippers to the arms. To align the correct angle, I made the arm and gripper parallel, and added a construction line down the center, to add the angles. Finally, I added the bolts through concentric and coincident mates.
