Impossible Passthrough Double Helix Fidget
Description:
This Impossible Passthrough Double Helix Fidget is a kinetic sculpture designed to print cleanly and reliably with no supports required. Its geometry creates an intriguing visual effect — a double helix that appears to contain an impossible passthrough channel.
The double helix itself is a static structure. Inside it, a continuous internal channel forms an impossible passthrough path where the inner shapes slide through the helix, creating the illusion that they pass through solid geometry while moving smoothly along the spiral.
Features:
- Double helix impossible geometry
- spiral sliding mechanism
- Four interchangeable inner shapes:
- Sphere
- Cone
- Cylinder
- Chamfered cylinder
- Designed for clean slicing and reliable printing
Printing:
- Print in place
- No supports required
- Can be printed in a single color or with multi-color setups for heightened visual effect
- Let the build plate cool before removing
Dimensions:
40x40x150mm

If you enjoy this Double Helix Impossible Passthrough model, you may also like the Twisty Fidget Cylinder. It is a different type of fidget — based on a linear sequence of interlinked segments moving inside a cylinder with a vertical passthrough hole, rather than a double helix structure. It’s a good way to compare how the same core idea feels in two very different mechanical layouts.
