lego neck joint

this is a neck joint that should be compatible with the small lego ball joints, this being inspired by my current lego project. and please tell me how well it works and what i can fix. this new version includes some ball joints as well as male and female stud connectors. its reecomended you flip the parts over 180so the ball joint and sockets point up, i feel thats the best way to print these but you may have a better one, either way enjoy, have fun, and PLEASE give me your honest opinion about
