If you like my design, check out my models below:

It is important to consider that there is a special edge that prevents the cover from touching the screen:

There are four small clips to prevent the screen from moving while it is opened:

There is a snap clip that holds the lid closed.

The lid stays open on its own.

For the hinge pin you can use the pin included in the print or a 3.15 mm diameter metal nail

The supports are only needed for the hinge of the fixed part of the cover
