Additionally, you will need 5 self-tapping screws: 4pcs M2.5x6 (boxes), 1pc M2.5x10 (center).
You will find attached an image showing the needed screws example and their parameters.

(Please disregard the blobs on the box walls - I just forgot to properly tweak the retraction parameters and the seam position).
