Easy Spinning Top

For my first ever Thingiverse thing I set out to make a spinning top toy that printed in one piece with no supports or raft required.

I went through a fair few iterations and a lot of testing to get one I am happy with, Spin time is ~40 seconds, I have had a few runs go over 50.

I am sure it can be improved, so if anyone has any ideas or wants to try something it is available on tinkercad : https://www.tinkercad.com/things/7SXE4wMd3UY-spinning-top.
