Ok got a problem. The 4 metal pieces are welded to the top, so there is no way to get the grommet out!!!
So the next step, and I don't think it is worth it...is to put a grommet on top of the other.
The problem is that it would have to be permanent so as not to move!
I am sure a piece of plastic or a metal possibly would do the trick. For me, I don't think it is that serious. I don't play games that hard, and this plastic piece at the bottom is likely to last 20 years!
Anywhere here is a picture for the idea. A small lip on top shows that it can be done. Look at both arrows to see what I mean.

This does work real good now without the top, and it doesn't feel cheap!
I still thank you for bringing this to my attention though. It was a pain to remove.
