We combine 2 wooden sticks and razors as in the photo with the help of silicone adhesive
However, you need to be careful, the middle bar will move between the blades so that the phone holder can expand
Then we put on the elastic rope that will make the movement.
Then we add a high stand to the phone holder with a plastic bottle
mobile phone holder is ready at the end, you can put water in the bottle to keep larger phones fixed
