From the designer:

This is a custom insert that I have designed to fit your Milwaukee Packout Drawers to store your M12 Gen 2 Drill and M12 Surge Impact. It specifically fits the Milwaukee 2 & 3 Drawer units (48-22-8443 & 48-22-8442).

This is the ultimate modular storage solution for your Packout Drawers! Files are provided for having your insert on either the left or right side. I will have many more designs to share for the drawers soon so you can mix and match your inserts to set up your own perfect drawer units!
