The video is just a simple demo to show how it can be done. Details will need to be done by you
I do not know if every box / profile / extrusion manufacturer provides 3D model. You may need to draw it by yourself and then create the panel with openings.
Panels are usually not difficult. For example, when I was doing panel for some of our boards, I even didn't create the exact extrusion shape, I just created a very simple shape and placed the board into the right height. Then I created empty panels with the right mounting hole position and did the openings. It's not a proper 3D model, but it worked well to create the panels.
