From the outside and inside it looks like a normal box. However, you can lift the false bottom in the box using a piece of filament or wire and feed it through the hole at the bottom. The secret compartment has space for dollar bills, keys, or any small item. The top compartment can also be used as additional storage if needed.

No supports are necessary. All parts can be printed in one print or separately if you want to adjust the size. All pieces are oriented, and ready to be printed. If a lighter filament is used, the wall count should be increased to reduce the transparency.
