This is my idea for hooks through foam to the wall. This is why hook is little bit smaller at the end.
To hooks I used a 50mm screw and wall stud which I had laying around.

Project was for fun, but I think its solid.

For finish with white color inside I just used glue and piece of paper.

I did not design holder for Quest 2 controllers, I remixed it from: https://www.thingiverse.com/thing:4740435

You can print hook and caps without support ofcourse, but I suggest little brim for hook.

You need support for hook for controllers.

Also I suggest printing 3-4 walls.
