Design Concept
This model is designed to help children develop fine motor skills and enhance hand–eye coordination. By using their hands to screw colored nuts onto threaded rods, kids can learn basic mechanical principles while enjoying a colorful play experience.

How to Use
Suitable for early childhood education settings or home environments, this product encourages children to engage in hands-on activities. Combining educational value with fun, it helps foster dexterity as children play.

Printing Recommendations
Use PLA filament and set the infill density to 20% to ensure durability. We recommend printing in vibrant colors to capture children’s attention. Make sure that the nuts and bolts fit securely and turn smoothly during assembly.

Assembly Instructions
Simply align the bolt with the corresponding screw on the base and tighten it. If you encounter significant resistance when screwing on the nut, gently remove any burrs or debris.
