Quantum Brick Fidget

YOU ONLY NEED ONE PIECE - THE SECOND ONE IS JUST ROTATED.

This is a 3D printed fidget toy called “Quantum Brick.” It’s a compact block made of multiple thin sliding layers, each with small tabs on top that allow individual movement using your fingers.

The layers slide back and forth, creating a smooth, repetitive motion with clear tactile feedback. The movement feels controlled and satisfying, making it ideal for casual fidgeting.

For full functionality, two identical bricks are required. They are used together, sliding against each other to create the intended motion and overall effect. A single piece will not provide the same experience.

The design is simple and intuitive, with no setup needed. It’s meant for keeping your hands busy, improving focus, or just passing time. The consistent mechanical feedback makes it suitable for everyday use.

PLEASE NOTE: This model was designed and modeled by me. Some modeling techniques were learned from public tutorials, however all CAD work and modeling were created by me from scratch.
