Impossible Passthrough Double Helix Fidget

Impossible Passthrough Double Helix FidgetDescription:This Impossible Passthrough Double Helix Fidget is a kinetic sculpture designed to print cleanly and reliably with no supports required. Its geometry creates an intriguing visual effect — a double helix that appears to contain an impossible passthrough channel.The double helix itself is a static structure. Inside it, a continuous internal channel forms an impossible passthrough path where the inner shapes slide through the helix, creating the illusion that they pass through solid geometry while moving smoothly along the spiral.
