This 3D-printed model is a cylindrical stress-relief toy that embodies striking industrial geometry. By dividing the cylinder into multiple independent modules with specific tilt angles and employing an ingenious mechanical assembly, it can transform in an instant—through twisting or stretching—from a compact cylindrical form into a sinuous, dynamic spiral chain. Throughout repeated pushing, pulling, and twisting, it delivers a smooth tactile experience and visually captivating shape transformations, while effectively relieving stress. It is a versatile desktop gadget that combines playful engagement with fingertip massage functionality.
