I got back my fixed boards and now they have correct power markings! No more guessing on that :)

I also remembered to put the SW1 marking for where the tilt switch goes, so that was a nice fix as well.

For my mounting holes, I found out my raspberry pi's mounting holes were about the right size for the screws that came with my case. They were about 2.9mm in diameter. I created a new mounting hole in kicad with the right diameter and replaced the old ones. Testing them was a success! So I think this board is pretty much finished.
