I agree with Dan, send Bosch the pictures. They may want to change the design or at least issue a warning about letting the blade contact it.
I like to make pushers similar to what Vince is showing except out of 1/4 to 3/8 ply. You cut it out so that there is a 1/4" or so hook left at the back of the bottom like the heel on a shoe. Since it's home made and usually out of scrap it doesn't hurt your feelings if you nick it. And you can usually cut a new heel a few times before it needs to be tossed.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
