Modular Drawer System

In development!!!Hi, I want to design a modular drawer system that uses less material, is quicker to print and wastes less space than the ones I have found so far.The first 30mm high module has just been drawn in the first version.As soon as I'm not printing out print jobs for friends and acquaintances, I'll print this for the first time.I'm asking for suggestions on which modules you would like.
