Infinity double ball with massage effect

This Infinity toy has small spikes. It stimulates the hands while playing and can be used like a massage ball.

New: When the spikes are folded outwards, there are pairs of spikes on the inside that interlock, making the ball more stable for massage.The inside is now also a ball.

Printing

Use PETG for the hinges. If you want a firmer feeling, use the hinges with “strong” in the name. These have a pretension of 3 %.

I only print the hinges with PETG-CF. Then they are super stable and still have the necessary elasticity.
