So I was OCDishly going over my P3S and noticed that I was able to tighten the screws on the motor mount (I think that's what it's called). They weren't loose or anything, but I was able to tighten them up a little. How tight should they be? Should they be as tight as I'm able to get them? I'm worried that if I were to tighten them too much I might accidentally strip something or that it might put stress on the frame and start causing hairline cracks that a lot of people seem to be having trouble with. Again, they weren't loose, but with a little bit of force I was able to get them to move. I didn't actually go and tighten them all, I just noticed it on a few of the screws and stopped there. They're probably fine and I'm just worrying over nothing again, but I just got this thing and am super worried about anything happening to it.
