Amazon Basics toolbox gridfinity base

This is a custom Gridfinity base for the Amazon Basics 2-Drawer Steel Organization Chest. It is offset to accommodate the lip overhangs of the chest.Cutout is allowed near the drawer lock hinge, and I have left the surplus space blank on left side.It's a tight fit to my specific toolbox, so I hope there's not a lot of variance in the construction of the chest.
