The original case wall mount was missing a cover and would expose the screws, making the mounting itself unsightly.
Screws must be flush as there is less than 0.5 mm clearance so use “flat screws” (example below).
I tested with the wall stand but others should work.
If your screws are too large and sticking out, try increasing the height of the model to compensate.
The author remixed this model.
The model is original and only used the stand as a reference for sizing.
