This 3D Printed Triangle Turns Flat Geometry Into a Moving Tunnel #shorts

You think this is just a flat 3D-printed triangle.

It isn’t.

The design is made from roughly 35 nested triangular frames that shift relative to each other when the outer structure is twisted.

In one position, the whole object looks almost flat. Rotate it, and those layers spread into a deep geometric tunnel, creating a moving optical effect without adding or removing any parts.

It’s a simple print with surprisingly complex motion.

~35 triangles hidden in one flat print.
