Ball and socket snap fit
Ball and socket snap fit
(OP)
I would like to know if anybody has an idea how to calculate all the parameters needed to properly design a ball and socket snap fit.
I have searched on the internet but I did not find any clear equation that explains the relation among the ball diameter, the socket diameter, the opening width and the material properties (I will use the ERTALYTE).
Thank you in advance for any proposition.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

The castellated socket can be roughly modeled as a rotational array of cantilevered fingers. The slots will probably have to extend past the ball equator in order to limit the bending stress.

For example: A "ball and socket" joint may need to be "hand-snapped" like a socket wrench. If so, measure how Craftsmen wrenches do it. Or it make need to be fully torqued and only machine operated.
