Design needs some more love, hight of the screwholes need to be larger otherwise the buttons wont work. 2- 9.5mm screws are too long you will see it starts to go through the front of the case. The part where you can place nuts are not of the correct size and should be 1 mm arround wider.
Button holes also to tight and you need to file them wider. Overall be prepaired to spend 1 hour in Blender to adjust the model.
