Ball end torx drive geometry 1

[BiPolarMoment]

I'm trying to model a ball end torx and I can't seem to find a good picture or a reference for what it looks like. I have a hard time visualizing what it must look like.

Modeling it is a whole other challenge.

Does anyone have any sources or suggestions?

Thanks.
