Description
I saw Makerblock's topic about the ball joint, I thought openSCAD was suitable and adviced it, but thought I'd give it a try myself. This is a very quick hack, but it can be easily modified since it's just code.
In OpenSCAD, you can choose to see an animation of the ball joint in action. Do this by uncommeting "demo();" and commenting "print();". To print it, choose the latter, press F6 and export to STL.
For a very cool implementation of this 'part' used in a camera mount, see thingiverse.com/thing:2631

Instructions
Modify it with the following parameters:
size=10; // size of the ball joint
joint_spacing =0.5; // some space between them?
joint_thickness = 2; // thickness of the arms
joint_arms = 5; // how many arms do you want?
arm_width = 10; // actually: how much is removed from the arms Larger values will remove more
size=10; // size of the ball joint
joint_spacing =0.5; // some space between them?
joint_thickness = 2; // thickness of the arms
joint_arms = 5; // how many arms do you want?
arm_width = 10; // actually: how much is removed from the arms Larger values will remove more

Very nice - I've got a windshield linkage that's broken on my car, due to poor (GM) design. This will be a good challenge, to modify your part and make it do what I need. We'll see how it goes.

Beautiful! Is the STL oriented just like the rendered picture? If so, the ball joint probably needs to be turned upside right to be printed.

Did it print?
The issue with the original one was that skeinforge die not like it.
More from Erik
I think there is a small failure.
The ball had not enough place inside. the joint. because it touched the cylinder on the bottom.
module joint2(){
difference()
{
joint();
sphere(r=size+joint_spacing);
}}
Just create a derivative. This was more a proof-of-concept showing how easy it was to make something like this in OpenSCAD. OpenSCAD at the time was still very new... Now it has matured more and there are more free solutions that do what *SCAD does.
