Updated Grip for Rubik's Cube Solving Robot

Updated the gripper file to allow for enough room to fit my servo arm. I purchased these servos from Amazon to rotate the cube, I thought they were the same as the ones recommended in the original design, but I had to increase the size of the servo arm slot for the parts to fit well.
