Develop a mechanism to stop a cam after one rotation

Appreciate help to develop a mechanism to stop a circular disc after it rotates 360 degrees. The disc (about 40mm in diameter and 3mm thick) is driven by a servo motor, which is controlled by a PCB. A push button elsewhere initiates the disc movement. I need the disc to stop after one rotation and be able to move again after the push button is pressed. Only 3D design is needed. I will print it out and verify. Thanks for bidding.
