Impossible Cone Fidget Set of 3 - Spiral Cone & Pyramid Passthrough Fidget | 3D Printed Sensory Desk Toy, Rainbow Silk, KAHAUS

The market calls these impossible cones, and this set has three of them: a pyramid, a pyramid twisted around its own axis, and a cone. Each is cut with a spiral track that lets the top section travel down through the body and return to the tip, looking as though it moves straight through a solid wall.

The motion is slow, smooth and completely silent - nothing clicks, nothing rattles, there are no springs and no batteries. This is a one-handed fidget: it keeps your fingers busy and leaves your head free during study sessions, desk work, long phone calls and winding down in the evening.

Every piece is 3D printed in a single part from silk filament. The surface has a soft metallic sheen and the colour drifts between shades depending on the light - the tone is in the material itself, so it cannot wear away or flake. About 7 cm tall with a 4.5 cm base; the set of three weighs roughly 112 g.

Three different shapes in one box make an easy gift for anyone who taps pens or cannot keep their hands still.

• THREE SHAPES, THREE DIFFERENT MOTIONS - a pyramid, a pyramid twisted around its own axis and a cone. Each has a different spiral pitch, so your fingers get three distinct feels instead of one repetitive gesture.
• THE IMPOSSIBLE-SHAPE EFFECT - the top section travels down a spiral track through the body and climbs back to the tip. It looks as if it passes straight through a solid wall - that is the passthrough, and the whole point.
• SILENT - NO CLICKING, NO SPRINGS, NO BATTERIES - it works on geometry alone. Spin it in a dull meeting, in a library or on a night train; nobody will hear that your hands are busy.
• RAINBOW SILK THAT SHIFTS IN THE LIGHT - 3D printed in silk filament, so the shade drifts between colours as the angle changes. The colour lives in the material, not in a coating: it cannot rub off or chip.
• ABOUT 7 CM TALL, 4.5 CM BASE - each piece fits in your palm and stands upright next to a monitor. Three pieces per set: one for the office, one for home, one to give away.
