Secret Box 3D Models: STL Puzzle Boxes
This collection gathers secret box 3D models: puzzle boxes with hidden locks, coin banks, game-themed cubes and animal-shaped containers. Most are made for 3D printing at small to medium scale, and the STL files come from several platforms. It helps you compare mechanisms and dimensions before you start a print. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Secret Box 3D Models: STL Puzzle Boxes»
The models differ mainly in how the hidden opening works. Some use sliding panels or a rotating key, others rely on magnets, press-fit pins or a lid that only moves in one direction. Coin banks add a slot on top of the same idea, while cube-shaped versions often hide the opening behind a printed face plate. Animal and nature shapes usually wrap the mechanism inside a shell, so the seam is less obvious.
When choosing a model, look at the mechanism description and the part count first. Check the outer dimensions and wall thickness, since a small box leaves little room for error in the moving parts. Read whether the author lists supports, print orientation and material, and look at photos of real prints to judge how visible the seams are. For boxes with tight tolerances, a smaller nozzle and a well-calibrated first layer matter more than speed.
If the results feel narrow, try related wording: puzzle box, hidden compartment, trick box, stash box, coin bank or container. Adding a theme helps too, such as cube, heart, castle, animal or keychain. You can also search by mechanism, for example lock, magnet or sliding lid, or by use, such as gift box or desk storage.
