Are you referring to the front side? Well, and I guess the view from the back side too? It seems like the CNC machine was just not having a good day, because the reason why it looks so bad is that I had to route out more space for the mounting plate to fit as well. It's going to be covered with Lexan so I'm not concerned that I made it look bad. Oddly, I encountered that problem with everything that had a recess, and I used a little hand router with the sandpaper attachment to clear out enough room for everything. It's just that in the case of this underside deal, I need to do it really evenly--if not terribly cleanly--or else the trackball will be crooked or not fit all the way or whatever. Or, worse, I blow through to the other side, and then I'm ruined.
