Better fit for the dot. No glue needed

I had the hardest time getting that dot to stay, even with super glue. The dot would fly off every time they'd drop it. I made a wedge fit. It's squeeze fit now and it stays in just fine without glue for me. Add a drop of glue for an even tighter fit. The downside is that the dot does now require a support, but it's a tiny little spot right smack in the middle of the dot.
