benhs1898 - Good to hear you got things installed!
How much did you have to grind the screws down? I can't imagine you had different screws than I did. Mine are on there nice and tight. The only height issues I had were due to me being lazy and not trimming the tactile switch pins before soldering the top. I did end up just clipping them after the fact and bending them out of the way as best I could. Then I made sure I didn't have too much solder build up. The copper lid was able to then sit flush with the aluminum box.

I did just check with a multimeter and the ground for SW1 is touching the screw. Because of the positioning and since the screws are domed they should never touch the negative and positive switch leads simultaneously. But insulating is never a bad idea. Electrical tape works of course but might raise the PCB too high. Alternatively there are varnishes and coatings you can use to achieve the same results.
MG Chemicals Red GLPT Insulating Varnish
MG Chemicals Urethane Conformal Coating
You could coat the bottom of the board or the screws. Both should do the trick.
There is also the possibility of switching out the screws if you want to use electrical tape and it causes to much height (I haven't tried electrical tape but I know it's not thin). The screws are #8-32 in size.
I'm a little behind but I should have a build guide and best practices write up put together here in the next few days to go over some of these items and more.
For those going forward if there are any questions please let me know.
