Twisty Sphere Fidget Toy

A spherical twist-style fidget toy designed for smooth motion and satisfying tactile interaction. The segmented structure allows the sphere to expand and twist into a dynamic spiral shape, creating a playful transformation between a compact ball and an extended form.   With a diameter of 80 mm, the model fits comfortably in the hand and works well as a desk toy, stress-relief object, or interactive decorative piece. The simple geometry also makes it quick and reliable to print.
