Ball joint generator
Generate a print-in-place ball-and-socket joint (captive ball + socket)
A ball on a stem captured inside a socket whose opening is narrower than the ball, so it swivels freely and cannot pull out — desk-lamp arms, phone mounts, poseable figures. It prints pre-assembled, the ball floating on a clearance gap all round. Set the joint count above one and the same unit stacks into an articulated arm, every ball already captured in the socket below it. Download a print-ready STL or 3MF.
