Print two swing drum balls. Recommend light supports for the swing drum.
Additional needs:
Two 10cm lengths twine, string, yarn, ribbon, etc. to attach the balls
Assembly:
Thread the twine through one of the balls and tie a knot at the bottom of the ball.
Thread the opposite end of the twine through one of the holes in the swing drum. Adjust the length so the ball hits the face of the swing drum. Tie a knot to secure. Trim excess twine.
Repeat with the second ball, but this time threading the twine through the swing drum in the opposite direction of the first. You'll end up with a knot on each side of the swing drum.
