Beyblade and launcher.

Original design from - https://www.myminifactory.com/object/zip-top-spinning-top-14005

Edit - Driger beyblade doesn't print all that well, the ring has weird hollow sections that don't play nice.

Launcher doesn't need supports but beyblade needs them from the build plate up.
20% infill should do to make it solid enough.
Scaled down 70% makes it roughly the same size as a beyblade, I haven't tried smaller than 70% (photo of the two is one at 100% and one at 70%)
