Puzzle Piggy Bank 3D Models: STL Boxes and Vaults

«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.
