When I tried printing the original ball and socket links, the socket pieces would snap off when assembled. So I made this stronger version which prints on its side. The friction fit is nice and tight. I did have one piece split lengthwise when assembled though, so this still isn't perfect.
I used ASA for my print, so I'm not sure if this will work with the more rigid PLA.
