Impossible Passthrough Cone Puzzle, 3D Printed Spiral Fidget

A cone that seems to defy physics. The Impossible Passthrough is 3D printed as two interlocking pieces, a slimmer male spiral that appears to thread straight through a larger female spiral, with fins twisting all the way from a wide base up to a needle sharp point.

• Two piece design with an impossible spiral illusion
• Fins twist from base to sharp tip
• Splits apart into a six petal flower shape
• Smooth crisp finish on every fin
• Compact desk ornament and fidget in one

Printed in PLA+ for sharp detail on every curve, it comes together at roughly 56mm across and 86mm tall so it sits neatly on a desk, shelf or bookcase. Choose a single colour for a clean sculptural look or two colours for extra contrast between the halves.

Printed and shipped from right here in Australia, ready to order in your choice of colour.
