Delta End Effector with longer arms

This is a Delta end effector with longer arms. The distance from the center of the effector to the arm holes is 28.75mm. I built a larger Delta printer with heavier arms and IGUS KBRM-03 ball joints (http://www.igus.com/iPro/iPro_02_0030_0000_USen.htm?c=US&l=en) and needed the extra length for the larger hardware.
