The Ball Bit from Beyblade X. Compatible with any Beyblade from the Beyblade X line.
Print with “Tree (Auto)” Supports, and keep Infill at 15%. There will be a bit of support on the inside part on the bottom (Where it is usually hollow) which you can remove with a small tool such as a toothpick.

I printed this with ELEGOO Basic PLA White, but it should work with most PLA filaments. Be advised as these are 3D printed parts, so they can get worn out faster than official products (They still hold up pretty well).
