Screw the spinner to the Helios tube. It possible to use only one or two.

To attach the crowns to the paper ball, first you have to insert the small one and after the large one into the ball, pinch it to reduce the circumference, and release it. There is a resilience effect which strongly holds the part to the paper ball.

Insert the Ogiv3 into the ball through the large hole, and turn it 20 ° three times. make sure the tips go under the crown at each twist.

I'm sure you already understood.
The threaded rod passes through the ogiv3, then you have to put the washers and finally screw the nuts strong enough but not too much.

And that's all !!!

The paper ball can stand up alone in the both side too... not bad for a ball.
