Lego cv joint / cardan ball (stronger)

Print it in ABS (255C), laid down with normal supports (on build plate only). 0.15 layer height, 3 walls, 100% infill at 100mm/s (or slower).
Use some sandpaper to clean it a bit after printing.

I have remixed the original design to be able to print it laid down without interior supports. The part is stronger this way.
