Piggy Banks with a Secret: 3D Models to Print

This collection gathers 3D models of piggy banks and containers that hide something: a coin slot, a concealed drawer or a second compartment. Most files are made for home 3D printing and come in a few parts, so assembly and closing method matter as much as the shape. It is useful if you want a small functional object rather than a display piece. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Piggy Banks with a Secret: 3D Models to Print»

The models fall into a few groups. Animal figures keep the familiar pig shape, sometimes with a removable plug or a screw cap underneath. A second group hides the opening inside something else: a book, a box with a sliding lid, a plant pot or a household item. Character and game-themed banks sit in between, often built around a cube or a ghost shape with a separate slot piece.

When choosing a file, look at how the money comes out. Some designs use a screw cap, others a magnet, a dovetail joint or a keyed lock, and each needs different clearances to work after printing. Check the part count, whether the author shows the model split for printing, and whether supports are needed for overhangs around the slot. The material and layer height listed on the model page affect how well thin walls and moving parts behave.

To narrow the search, try words for the closing method as well as the object: hidden compartment, secret box, lockable bank, coin slot, screw cap, puzzle box. Related searches include stash box, jewellery box, desk organiser with a drawer, and containers shaped like food, tools or characters. Combining a theme word with a mechanism word usually gives shorter, more relevant result lists.

FAQ

Perguntas frequentes

What makes a piggy bank model "with a secret"?
Usually it means the opening is not obvious: a hidden drawer, a sliding panel, a book-shaped shell or a compartment inside another object. The coin slot may be visible while the way to empty the bank is concealed.
How do I empty a printed piggy bank?
It depends on the design. Common options are a screw cap on the bottom, a plug, a magnet-held lid or a sliding base. Check the model page to see which one the author used and how much clearance the parts need.
Which material works for a locking or sliding mechanism?
Rigid filaments such as PLA or PETG are typical for boxes and caps, since flexible ones can deform and jam moving parts. The author's page usually lists a material and settings that were used for the model.
Can I scale a piggy bank model up or down?
Yes, but scaling changes wall thickness and the fit of lids, threads and slots. If you resize, check the clearances again and test the closing parts before printing the whole body.
