3D Puzzle UGears UGE 412059 Treasure Box 354 Pieces

The UGEARS 3D Puzzle Treasure Box is a mechanical wooden model that assembles into a functioning lockable box designed to store small items such as jewelry, a flash drive or a set of keys. The assembled model measures approximately 142 mm in width and consists of interlocking plywood parts that form gears and a lid mechanism activated by an integrated key and hand lever.

Advantages

The model combines a hands-on construction experience with a usable storage box: assembling 354 precision-cut plywood pieces enhances fine motor skills and problem-solving, while the finished Treasure Box provides a mechanical locking and opening mechanism without glue or electronics. The wooden construction and visible gear movement demonstrate mechanical principles in a compact decorative object.

Suitable for

• Hobby model building
• Educational demonstrations of gears and mechanisms
• Safe storage for small personal items
• Gift for teens and adults interested in mechanical puzzles

Key specifications

• Model type: Mechanical 3D puzzle (Treasure Box)
• Number of parts: 354 pieces
• Recommended minimum age: 14 years
• Material: Plywood
• Approximate width: 142 mm

How to use

Assemble the plywood parts following the included instructions to create the box with its integrated gear system. To place items inside or reveal the contents, insert the carved key into the front locking mechanism and turn it counter-clockwise, or spin the wheel gear toward yourself or press the hand lever; any of these actions will engage the internal mechanism and lift the lid. Holding the hand lever longer will reverse the movement: the lid will close as the internal compartment lowers and the gears rotate in the opposite direction.

Usage recommendations

Assemble on a flat surface with good lighting. Handle small parts carefully and keep away from children under the recommended age. For smooth operation, ensure gears are correctly seated during assembly and avoid forcing parts; periodic gentle cleaning of dust will keep the mechanism working reliably.
