The original design is a golf ball, which was downloaded from GrabCad by "Bass":https://grabcad.com/library/i-made-a-golf-ball

It is recommended to use TPE material for printing to maximize the softness of the ball. In addition, you can first gently knead the pellets with your fingers to properly disperse the internal filling structure, which will yield better results.

!!!!! Warning!!!!!
The impact force of these balls is quite significant! I strongly recommend wearing protective goggles! I only allow my son to throw them at me, and I usually use them to hit outdoor targets.
