spinning disk top / gyroscope, three-part, can be assembled without gluing

This spinning top prints without support or other special configuration. The three parts can be easy assembled without gluing.
This one has a disk instead of spokes.

Here you can see, how long it spinns (about 105 sec.):

Please take also a look at my other spinng top, which turns not so long as this one, but has a nice spoke look.,
