Clacker

This is a simple percussion instrument. Twist the handle to make the balls strike the resonator. Supports are needed for underneath the resonator. Feed a string through one of the balls (flat side toward the resonator) and then through the resonator and onto the other ball. The string should be long enough to allow each ball to hit the center of the resonator. This model was inspired by a similar one created by 3Dprintbunny.
