Grass Block Twisty Fidget

At first glance, it’s a familiar grass block; Then it moves.

This design reimagines the iconic cube as a transforming mechanical object. With a smooth rotational motion, the compact block expands into a vertically staggered terrain formation - revealing layered geometry inspired by cliffside landscapes. Collapse it back, and it returns to a clean cube.

It’s equal parts display piece, kinetic sculpture, and tactile puzzle.

Design Intent

The goal was not just to make a fidget, but to engineer a controlled transformation:

• Precise segment alignment for consistent rotational travel

• Balanced internal tolerances for smooth motion

• Visual continuity between cube and expanded terrain form

• Strong structural integrity once assembled

The transformation is deliberate and satisfying — not loose, not gimmicky.

Printing Configurations

• AMS Version (Multi-Color Integrated Print)

• Non-AMS Version (Superglue the grass onto the bown mud block)

Both versions are dimensionally identical in motion and function.
