General Description

It’s a compact, square-shaped fidget toy with a built-in clicking mechanism.

The size seems to be roughly 3–4 cm per side (about the size of a coin holder).

The toy has a rotating cam-like slider inside the square housing, which moves along a curved track and produces a tactile "click" feedback when pushed

Main Components

1. Outer Housing (Frame)

Square, with slightly rounded corners.

Two different textures are visible:

Left one: smooth, matte beige finish.

Right one: rougher, textured blue finish.

It has a curved slot on the top (almost like a smile shape) which exposes the moving internal part.

At the bottom edge, there’s an opening where the clicker peg protrudes.

2. Internal Rotating Part

This is the main mechanism.

It’s a half-moon shaped wheel that rotates inside the housing.

Attached to it is a protruding peg/lever that the user pushes back and forth.

The peg slides along a curved track (the arc cutout at the top), causing the mechanism to "snap" from one detent to another.

3. Clicking Peg / Lever

Sticks out at the bottom edge.

Colors differ between the models shown: brown on the beige toy, neon yellow on the blue toy.

Ergonomic enough to push with a thumb or finger.

Provides the tactile "click" sensation by moving the inner cam against spring-loaded (or flexing plastic) stops.

Clicking Mechanism

Inside, the rotating part likely has detent bumps (or a gear-like ridge) that interact with small flexing tabs built into the housing.

When the peg is pushed, the bumps pass over these flex tabs, creating a resist–release–snap effect (similar to the feel of a ratchet).

Each movement along the track produces one click.

The arc shape means the peg doesn’t spin 360°, but moves back and forth in a limited sweep angle (about 90–120)

Design & Printing Notes

Printability:

Likely designed as a two-part snap-fit assembly (housing + rotating piece inside).

Some versions may use multiple colors if you have multi-material printing, but single-color works too.

Clearance:

Needs tight tolerances for smooth sliding without too much friction.

Around 0.2–0.3 mm gap between housing and rotating part is typical for FDM printers.

Feel:

The click strength depends on the flexibility of the plastic tabs and the detent profile.

PLA gives sharp clicks, while PETG or nylon may feel softer.

Function

Acts as a tactile fidget toy.

Provides repetitive clicking motion, similar to a pen click or switch toggle.

Pocket-sized, durable, and silent enough (depending on material) for casual use.
