This is a Pushrod fitting for the Anycubic Predator, it is stronger than the original one, that brokes me off in similar occasions. And its so difficult to get this piece without buying the entire Rod. So I decided to make one on my own. After the Print is done, you only have to put in a Brass Knurl Nut M4 in the Fitting Then cut out a Screw M4, that can fit in the Brass and in the original Fish eye. That´s it.
