Con quay Vĩnh cửu Eternity Spinning Top

Eternity Spinning Top features an optimized mechanism for prolonged spins and tricks, interchangeable tips, and a customizable design, offering a unique and lasting play experience. Use it with care and follow the assembly instructions below.

Printing Tips:

• Quality and Durability: Print all parts with 3 perimeters to enhance impact resistance.
• Customization: Experiment with different colors or change the filament in the body and cap for dynamic decorative effects when spinning.
• Optional Lubrication: To optimize the spin, you can apply a lubricant to the nail. Recommended options include:
  • Silicone Lubricant: Reduces friction without damaging the filament.
  • Dry PTFE (Teflon) Lubricant: Provides effective lubrication and keeps surfaces clean.
  • Light Oil: Such as machine or mineral oil, applied sparingly.

Materials Needed:

• A steel nail of 2 mm diameter and 40 mm length.
• A string approximately 2 mm thick and 140 cm long.
• Optional: Glue to secure the tip and prevent it from coming loose.

Assembly Instructions:

Nail Insertion:
Insert the steel nail through the internal hole of the body from the top.

Cap Installation:
Screw the cap onto the body. This locks the nail in place while allowing it to rotate, serving as the top's axis.

Tip Installation:
Insert the interchangeable tip until it is fully seated. Ensure that the tip of the nail is not exposed, as this could be dangerous. For added security, using glue is recommended.

String Setup:
Assemble the string as in the images. The plastic ring on the upper end simplifies the winding process.

Performance:

In testing, this top achieved over 30 seconds of spin in the palm of your hand and more than 60 seconds on a flat surface, showcasing its stability and efficiency.

This design is perfect for enthusiasts of traditional toys and 3D printing alike, offering a creative project with endless possibilities for customization. Enjoy assembling and personalizing your spinning top!
