This is a folding stand I use for my Nintendo Switch when I travel, so I can set it and connect it to any TV (I have a power adapter that also replaces the dock).
To assemble the hinges, use a piece of filament and melt the ends.
You may need to print with supports where the hinges are (my 1st print isn't super nice, I'm still playing around with the parameters for Overture's PETG).
The author marked this model as their own original creation.
