Spiralized Cone Impossible Passthrough
Defy Logic, Delight Your Hands
The Spiralized Cone Impossible Passthrough is a mind-bending, 3D-printed desktop fidget toy that looks like it shouldn't work — and that's exactly what makes it so captivating. This two-piece passthrough fidget features a spiralized cone structure where both separate pieces pass completely through each other in both directions — fully detaching and re-engaging in a feat that seems geometrically impossible yet flows with a smooth, satisfying motion every time. A guaranteed conversation starter on any desk, shelf, or tabletop, it's the kind of object people pick up and can't put down.
