The file 'Union Nut With 4 Grips For Generic Ball Joint 3D Printer Model' is (stl) file type, size is 136.7KB.
When I had designed a generic ball joint (which I needed of a mobile phone holder in my car) I figured that it worked much better than I had thought. That got me interested and I developed this special union nut with 4 extra strong grips to see if that would lock the joint even better... and it did ;-)
The original ball joint was published on my main page at Printable if you are interested:
