Articulated Fidget Keychain Spongebob Squarepants (Purely 3D Printed, No Hardware)

1. This model's arms and legs are connected by an integrated, articulated mechanism as shown in Figure 1. An articulated model.
2. It can be used as a decorative ornament, placed on a desk. During moments of idleness, boredom, or frustration, you can pick it up, move its arms or legs, and watch it wave its tiny hand in a gesture of victory—a way to alleviate minor stresses.
3. Alternatively, you can attach 3M tape to its back and stick it to a wall, door, refrigerator, or glass surface, using it as a key hook. Swing its little hand as you leave or pass by to uplift your mood.
4. Figures 1 through 8 are assembly diagrams.

5. The only notable point is the spring (blue part) installation location, shown in Figures 4 and 5.

   The upper end of the spring is mounted at the top of the back, as shown in Figure 4.

   The lower end of the spring is mounted on the raised platform connected to the foot.
