About this 3D model

I made a toy that I played with as a child, a string-pulled spinning top, except the one I played with as a child would light up, this one only has the most basic function. It is recommended to replace the string with a more resilient one, which can avoid excessive pulling, which may cause the string to be worn and broken, and even injure yourself. Assembly steps: 1. Cut 2 pieces of cotton string each 45cm long for later use. 2. Tie the cotton string to the pull ring. (Note: Be sure to tie it tightly to prevent it from coming loose when pulling! It is recommended to tie a secure knot!) 3. After fixing the two strings, pass them through the hole in the middle of the spinning top in parallel (as shown in the figure): 4. After passing through the hole, fix them in parallel to another pull ring. (Note: Be sure to tie it tightly to prevent it from coming loose when pulling! It is recommended to tie a secure knot!) 5. Once the strings are fixed, you can play happily. (*^▽^*)
