These compact cubes pack several mechanisms into one object:



Common cube features:

- Clicky buttons

- Switches and toggles

- Rolling balls

- Gear sides

- Joysticks or dials



Design tips:

- Use separate, snap-together parts to allow moving mechanisms.

- Consider printing in multiple colors for visual variety.

- Ensure enough clearance between moving parts (e.g., 0.2–0.3 mm on FDM printers).

### 3. Sliders, Switches, and Clickers



Quiet, pocket-friendly and great for subtle fidgeting:



Examples:

- Linear sliders with magnets or detents

- Rail sliders with springy resistance

- “Infinite” clickers and rocker switches



Design tips:

- Use curved or angled surfaces where fingers rest.

- Design stops or end caps so parts don’t slide off.

- For a smoother feel, polish sliding surfaces or slightly increase clearances.

### 4. Flexi Toys and Articulated Chains



These print-in-place designs move right off the build plate:



Types:

- Flexi dragons, snakes, lizards, and animals

- Articulated chains and bracelets

- Bendy cubes and lattice structures



Design tips:

- Ensure enough clearance between joints (often 0.3–0.5 mm).

- Use a brim if parts have small feet that might release from the bed.

- Avoid excessive overhangs within joints to prevent fusing.
