My idea was to design holder, which will be useful in windy weather, when i want to have open doors.

For me it working properly, so i hope it will be also useful for you. Assembly is pretty simple as you can see on attached pictures. Between part(1) and part(2) is small clearenace in order to make assembly possible and also to secure litle bit of movement for part(2) to the sides. Part(2) could be probably litle bit bigger, but for my purpose it is enough.
