## Long description

The Extra Digital mechanical lockbox is a sophisticated wooden assembly kit designed as a comprehensive STEM educational toy. This DIY construction set enables users to build a fully functional mechanical safe, providing a hands-on learning experience that bridges the gap between theoretical knowledge and practical engineering. By assembling this model, users gain insight into the mechanics of locking systems, mathematical combinatorics, and the importance of precision in construction.
Advantages
This kit offers a unique combination of entertainment and education, serving as both a challenging puzzle and a practical storage solution. The assembly process is designed to be intuitive, requiring no glue or specialized tools, which makes it accessible for young builders while still providing a rewarding challenge. The use of high-quality, laser-cut wooden components ensures durability and a smooth finish, allowing for further personalization through painting or decoration. Beyond the assembly, the finished safe functions as a real security device, teaching children the principles of cryptography and the importance of secure storage in a tangible way.
Suitable for
STEM education at home or in school environments
Developing fine motor skills and hand-eye coordination
Learning the basics of mechanical engineering and logic
Storing small personal items or savings securely
Gift-giving for hobbyists and students interested in mechanics
This kit may not be suitable for children under the age of 6 due to the presence of small parts and the level of dexterity required for assembly. It is also not intended for use as a high-security safe for valuable items, as it is primarily an educational model made of wood.
Key specifications
Material: High-quality non-toxic laser-cut wood, metal, and plastic
Dimensions: 130 x 80 x 80 mm
Weight: 140 g
Mechanism: 3-digit combination lock
Assembly: Glue-free construction
To assemble the lockbox, follow the provided manual step-by-step to ensure all components are aligned correctly. Begin by identifying the wooden parts and preparing the mechanical elements. Use the included screwdriver to fasten the parts together, being careful not to overtighten the screws, as this may affect the movement of the gears. Once the internal mechanism is set, test the combination lock before fully securing the outer panels to ensure smooth operation.
What to consider before purchase
Ensure the user meets the recommended age requirement of 6 years and above
Verify that the workspace is clear to prevent the loss of small components
Consider the time required for assembly, which may vary based on experience
Note that the safe is a mechanical model and should be handled with care
For the best results, take your time during the assembly process to understand how each gear and lever interacts. If the mechanism feels stiff, check for any misalignment or adjust the tension of the screws to ensure the lock operates smoothly.
