Wooden Puzzle Box with Combination Lock – 3D DIY Safe Model Kit

This wooden puzzle box with a combination lock is a build-it-yourself safe you assemble from 111 laser-cut pieces. It makes a thoughtful gift for teens and adults who love hands-on projects, and once it is built it keeps small treasures behind a dial-and-knob code.

Unlike a ready-made jewelry box, a wooden puzzle box is something you make yourself: you press out each part, fit the gears together and watch the safe take shape on your table. It is a relaxing evening project, a fun challenge to share with a partner or a friend, and a keepsake you can actually use afterward.

Every wooden puzzle box in this kit comes as flat sheets, so the fun starts the moment you open the package. Take your time, work one step at a time, and enjoy the satisfying moment when the door and the combination dial finally line up. When you are done, the wooden puzzle box becomes a small secret safe for the things you want to keep close.

Why You’ll Love the Wooden Puzzle Box

• Hands-on and screen-free: about 1.5 hours of building from flat wood sheets to a finished 3D safe.
• A working combination: the front dial and knobs turn to open the door, so the box is a puzzle before and after you build it.
• Room for small keepsakes: store notes, cash gifts, jewelry or a surprise for someone special.
• Looks great on display: the natural wood finish and visible gears suit a desk, shelf or office.
• Easy to give: everything comes flat-packed with instructions and sandpaper.

How It Works

1. Press the wood pieces out of the 5 boards and smooth any edges with the included sandpaper.
2. Follow the illustrated instructions to assemble the walls, the door and the dial-and-knob mechanism.
3. Close the door, then turn the dial and knobs to the right combination to open your new safe.
