Twisted Pyramid Fidget - Spiral Passthrough, Impossible Shape | 3D Printed Sensory Desk Toy, Rainbow Silk, KAHAUS

The market calls this shape an impossible pyramid. It is a twisted pyramid 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, no springs and no batteries. It works during study sessions, desk work, long phone calls and winding down in the evening.

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, 4.9 cm base, roughly 40 g.

An easy gift for anyone who taps pens or cannot keep their hands still.

• 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.
• ONE TWISTED PYRAMID, ONE RHYTHM - a single spiral pitch means the motion is repeatable and predictable. A one-handed fidget that keeps your fingers busy and leaves your head free.
• 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, 4.9 CM BASE - fits in your palm and stands upright next to a monitor. At roughly 40 g you can carry it anywhere without noticing it.
