UPDATE 9.Jan.2019: Now with TOP BAR and DISPLAY COVER!
The back stand can be folded almost to the back. It is portable now.
I hope you find out for yourself how to assemble those 3 parts together.
Use a long cross bar to fix the cover by putting it through a top bar hole and then through
the cover hole(s) when it is over the display. (Image will follow.)
WARNING: Put a towel between the cover and the Switch display (fix it on the cover part)
You should have a transparent display cover on your Switch anyway.
