Puzzle Piggy Bank 3D Models: STL Boxes and Vaults

This collection gathers 3D models that work as both a coin bank and a puzzle. Some hide the opening behind a maze, others need a sequence of turns before the lid comes off. It is useful if you want a 3D printing project that stays interesting after the last layer. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

Informazioni sulla categoria

«Puzzle Piggy Bank 3D Models: STL Boxes and Vaults»

The models fall into a few groups. Simple banks keep a visible slot and a removable base, while labyrinth versions route the coin through a channel before it drops inside. Puzzle boxes use sliding plates, rotating rings or hidden pins, and character-shaped banks borrow the outline of a game or film object. Piece-assembly designs arrive as several parts that stack or interlock into the finished body.

Before printing, read the author's page for the wall thickness, the clearance between moving parts and the number of separate pieces. Tight tolerances that work on one 3D printer may bind on another, so check whether the files are split for assembly or meant to print in one go. Look at the material and settings the author lists, and at photos of real prints, to judge how the mechanism behaves after the layers cool.

If the results feel narrow, try related wording: savings box, coin vault, money box, maze box, trick lock or secret compartment. Combining a puzzle term with a shape or theme usually narrows the list faster than adding adjectives. You can also search by mechanism, such as sliding lid, screw lid or rotating dial, and by the object the bank imitates.

FAQ

Domande frequenti

How does a puzzle piggy bank differ from a normal one?
The coin slot is usually hidden or blocked until you solve a maze, slide a panel or turn a dial. A plain bank only needs a lid or a plug at the bottom.
Do these models need supports?
It depends on the design. Overhangs inside a maze channel or under a sliding plate often need them, while flat-sided boxes may not. The author's page usually states what the model was sliced with.
What should I check before printing a moving mechanism?
Look at the clearance the author gives between parts, the recommended layer height and whether the model is split into pieces. Printing a small test of the moving section first shows how your 3D printer handles the gaps.
Can I scale these models up or down?
Scaling changes wall thickness and the clearance between moving parts, so a mechanism that works at one size may jam at another. Check the author's notes before changing the scale.
