I created this drawer dividers. Just print a few of them and then put them together crosswise so that they form individual compartments. This means you can choose the size of the compartments in your drawer yourself.
The size of a single partition is 20 centimeters x 8 centimeters.
The gaps are 3 millimeters wide and the height is 2.9 millimeters.
They can be easily cut to fit exactly into almost any drawer.
