The feature of this pokemon ball is that it is small. It is approximately 35mm. 
The original version was very beautiful, but when it was made smaller, the fittings did not work. 

I renewed the fittings. 
To reduce black filament consumption, 
I turned the inner part of the pokeball into a ring. 
I made the bottom flat so that it could stand on the ground.
 And I left a hole in the base so you can insert a 5mm*1mm magnet if you want. 

Note: Adhesive is required to assemble the parts. 
You can use 1.75mm filament for the connection part, just like the original. (R C 3D for this clever idea Thank you.)
