Optimized 3D Printed Ball and Socket Joint

thingiverse

This is a tweak of my 2 lobed design with two pieces that interlock to make a 4 lobed socket. This allows everything to print flat for maximum strength. Layers shouldn't split with this design since the lobes are vertical like on most ball joints. The one downside to this design is that hex screws no longer fit, and you have to use flat head screws. #6 and #8 should both work. Roughly equivalent to 3mm and 4mm.
