Abstract:
1. An apparatus comprising: a first component having a circular opening with an interior chamfered edge, the first component having a circular bottom surface within the opening and below the chamfered edge; a second component positioned within the circular opening, the second component having a circular base, the second component further including a side surface adjacent to the circular base, the side surface being complementary in shape to the internal chamfered edge; a magnetic feature adjacent to the circular bottom surface; wherein the magnetic feature provides a magnetic pull force in a first direction to secure the second component within the circular opening while allowing the second component to rotate within the circular opening, and the second component is configured to break away from the magnetic pull force when a contact force applied to the second component in a second direction is greater than a threshold force.
