Query: Broken after 2nd Use!

This juicer worked well the first time I used it, but I just used it for the second time and it is broken! Aside from the shaft that fits into the mixer, the entire unit is made of plastic. The "pin" that slides in near the thumb screw is also made of plastic. I don't understand why it it not metal because that little nub of plastic is the only thing that holds the outside juicer attachment in place. Mine just sheared completely off during the 2nd use. When this happened the entire juicer attachment began spinning around throwing pulp and juice everywhere. I LOVE my kitchenaid mixer, but I am extremely disappointed with the design of this product.
