I’m trying to print a ball joint in one pass, yet still have the parts movable.
I’m printing a model of a mech, which has a ball & socket hip joint (see image below).
The obvious way, would be to print the socket piece in 2 halves, and the ball separate, then glue the two halves after I put the ball inside.
But I’d like to try to print them as one piece, with the ball inside the socket, and with just enough clearance between the parts, that they don’t stick together.
Question: what is the minimum gap I need to leave between the ball and socket, so they print as separate parts (not touching), yet it’s still a relatively tight fit (not sloppy)
