About this 3D model

This object was made in Tinkercad for the MyMiniFactory competition in fidget spinners. https://www.tinkercad.com/things/65NKlvk85OS Each inner ring is a two-axis gimbal allowing external rotation and manipulation of the 608 bearings. I have also made this model with only the center containing a gimbal: https://www.myminifactory.com/object/gyro-spinner-2-in-1-with-grip-38191
