About this 3D model

This Large double bearing is another experiment in the developments of my other bearing and gyroscope models.Gyroscope Photo Frame Gyroscope Impossible Bearing 2.0 The balls here are larger, as is the thickness of the object, because of this the impossible bearing has only 2 rings as apposed to 3. This does however make it a much smoother model, easier to print and better spinning movement in all directions.
