This is a kinetic art Zen garden where you hold the ball off center and release to let the ball create patterns in the sand. With a rake and hoe to smooth out your stand. I designed a spirograph ball that is all 3d printed as well as a 3d printed holder for a ½ inch metal ball. I suggest using a clear fishing line an the metal ball which I will link below. Just glue the metal ball into the holder. The hole for the string is on the post that runs below the top member of the gate.
If you like this design please leave a make and give a follow. If you have any suggestions for a revision please dm me. Hope to see some makes!
