Scary moving eyes

No supports are necessary. The parts are simple and connected with M3 bolts and nuts (see photographs). The rotation direction is reversed when the switch is activated by the arms attached to the eyes. The geared motor (AliExpress) is low RPM. To make the eyes more realistic, a small lens can be inserted. Paint the inside of the eye black for a more natural look. Make it extra spooky by installing an led in each eye, add a mouth, teeth, a nose etc.
