We started making the self opening box by poking two holes for the servo motor. We then threaded the wires through for the motor making sure to leave enough slack in the line to re position the motors. We first tried mounting the servos inside on the bottom surface of the box and ran thin wire outside of the box to "pull" the box open. Our hope was that we could hide the motors with a false bottom, so it would look like a more finished produce. After struggling to get this working, we changed the design by moving the motors higher.
