Improved Ball and Socket
thingiverse
I've created my most refined version of a modified ball & socket joint perfect for designing articulated figures. The built-in ball & socket components in Tinkercad are passable, but I've discovered that they tend to loosen over time. I aimed to craft a joint that would provide decent articulation while staying securely connected when posed or manipulated. This design features a ball with two small tabs that line up with corresponding slots in the socket. If the ball is twisted after entering the socket, it should firmly lock into place and enable a reasonable range of motion.
