Boost MeThanks

Create your own 40 mm spiky massage ball with this easy-to-print design!
This spike ball is designed in three parts that snap together without glue.

The model consists of two spiked hemispheres and a central cube connector.
Each hemisphere contains a square socket that perfectly fits the cube, creating a tight press-fit assembly. The parts lock together securely, but glue can be added if you want a permanent bond.

Supports are only required inside the square holes of the hemispheres. These supports are easy to remove with small pliers.

The finished ball is great for:

• Hand massage
• Muscle relaxation
• Stress relief
• Grip exercises

Compact, satisfying to print, and fun to assemble!
