Diabolo for 3 D printing

Hi everyone.

here a design wich is not attended to be new.
It is very simple and may probably look exactly the same as others.
But I just made it from scratch.
A separate mount system to be put along the wheel of the diabolo will be separately published.
I consider that one can print only the diabolo if one wish.

I did not print the diabolo yet.

Regards

Froggy.
