Polystyrene POKEBALL case

This is a simple button for my Pokemon case, made mainly out of polystyrene. The button (3d printed) is a WIP, and it does not integrate any locking system for the case (It is just for show).
You can see me work on it here: https://youtu.be/RlaMNROyDVw.
and here : https://youtu.be/u-CZI5twvIo
I included the sketch, the foam rings files, the 3d button, so you can make one.
The video is just the first part of the build. I still work on the finishing part of the box.
