I modified the original to use 3M Command Strips instead of screws. I filled in the screw keyholes and elongated the bottom pieces to fit two large strips. One each should be enough… but this is for my nephews who can be a little rough. Probably a good idea to use 4 total, anyway. The top piece doesn't bear weight and uses a single medium strip, or a large strip would also work.

To place the strips on the wall, first put them on the wall mount. Then hold the bottom two pieces and the PS4 together, and place it against the wall. Give them a good press, remove the PS4, let them set for a few minutes, then do the same thing with the top piece. The top piece has some leeway to the left and right, as long as it's straight and far enough down so the top sits low enough to prevent the PS4 tilting forward.

PETG recommended over PLA.
