I made the back thicker and made an edit to give the board a tiny bit more space and there was a part that was hovering on the build plate I made flat. I also made the holes a lot tighter and tapered for screwing into without the use of inserts. Printed with PETG with a bit of work m3 screws will work for the case parts and m2/m2.5 screws should work well when securing the Pi itself.
