This is a mirror/motor module for a laser Spirograph system. The mirror is set to a 3 Degree angle. To attach the mirror to the disc use a small peace of double sided tape. The motor is attached to the motor_mount using double sided tape and a cable tie. This will help to limit the noise generated from the motor. The motor used in the picture above, is from a computer CD drive. Most cd players will have this small motor in it. Update:
