SANSGOUP Impossible Cone (3 Pack) – 3D Printed Spiral Cone Fidget Toy, Passthrough Sculpture, Laser Blue Green

The SANSGOUP Impossible Cone set includes three 3D-printed PLA passthrough sculptures (cone, pyramid, cylinder) that create an optical illusion of solid forms passing through each other. Designed by RJ Designer, these mini desktop fidget toys are intended for stress relief and creative stimulation, suitable for both kids and adults.

What makes the Impossible Cone a mind-bending fidget toy?

Each piece in this set features a spiral cone design that tricks the eye into seeing two separate parts seamlessly move through one another. The effect is both visually striking and intellectually engaging, making it a conversation starter on any desk or shelf. The twisting and turning action provides a satisfying tactile experience that can help improve focus during work or study.

Materials and build quality

These sculptures are made using state-of-the-art 3D printing technology with PLA plastic, a durable and eco-friendly material. The printing process produces vibrant colors and precise geometry. Due to the nature of 3D printing, the pieces may require a brief break-in period: rotating them a few times helps smooth out the movement.

• Material: PLA plastic (3D printed)
• Shapes included: Cone, pyramid, cylinder
• Color: Laser Blue Green
• Designer: RJ Designer
• Intended use: Fidget toy, desktop decoration, stress relief

Three shapes in one set

Unlike single-shaped fidget toys, this pack offers three distinct geometries: a cone, a pyramid, and a cylinder. Each presents a different visual illusion and handling feel, adding variety to your fidgeting routine. The set is compact enough to fit in a pocket or bag, making it easy to carry to the office, school, or on trips.

Tips for getting the smoothest rotation

If a piece feels stiff initially, manually rotate the inner and outer parts several times. The PLA material naturally wears in slightly, allowing the passthrough action to become more fluid. Avoid applying excessive force or dropping the pieces, as 3D-printed parts can be brittle if mishandled.

Who is this gift suitable for?

This impossible cone set appeals to a wide audience: kids curious about illusions and geometry, adults seeking a desk toy for stress relief, and anyone who appreciates clever design. It also makes a thoughtful gift for art lovers, science enthusiasts, or collectors of unique gadgets.
