Infinity ball with massage effect

new version available: Infinity double ball Infinity ball with massage effect This infinity toy has small spikes. It stimulates the hands while you play with it and can be used like a massage ball. Printing Use PETG for the hinges. If you like a firmer feel, use the hinges with “strong” in the name. These have 3% pretension. I only print the hinges with PETG-CF. Then they are super stable and still have the necessary elasticity.
