Khớp Ball and Socket Tham Số với Vòng Khóa (Locking Ring)

This file was made in a naive attempt to generate ball and socket joints directly from the original file. If you use the original file (not this remix) as a library in your project, you'll likely be much happier, but I'm leaving this for posterity, or in case it proves useful to some of you someday in a somewhat bizarre set of circumstances.
