3D puzzle UGears Safe 179 pcs Width 196 mm Height 176 mm

UGears Wooden Safe is a mechanical 3D puzzle kit that assembles into a functional wooden safe with a working combination lock. The model consists of 179 pieces and, when built, provides a compact storage box sized approximately 196 mm wide and 176 mm high for small personal items. The kit is designed to demonstrate the mechanics of tumblers, drive spindles and fences while offering a repeatable hands-on building and lock-manipulation experience.

Advantages

The UGears Safe combines a detailed wooden construction with a real mechanical combination mechanism that can be opened by turning the knob and listening for clicks. The kit requires no glue, uses precisely cut wooden parts, and doubles as both an educational demonstration of lock mechanics and a usable storage box. With clear instructions, the model supports step-by-step assembly and repeated practice of opening the lock.

Suitable for

• Puzzle and model-building enthusiasts
• People learning basic lock mechanics and manipulation techniques
• Gift buyers looking for an original, interactive present
• Hands-on learners and hobbyists seeking engineering challenges

Key specifications

• Piece count: 179 parts
• Assembled dimensions: approximately 196 mm (width) × 176 mm (height)
• Material: laser-cut wood
• Mechanism: mechanical combination lock with tumblers and rotating knob

How to use

Follow the included assembly instructions to build the wooden safe step by step.
