The Lowe's Mini Toolbox is perfect for adding a 3x5 Gridfinity baseplate in each drawer to use x3 and x6 height bins. I've modified one of my Clickfinity baseplates to incorporate spacers on each side; none are needed for the front and back. As there are bolts in the back of each drawer, you will need to use one of the modified bins if you are adding one that goes to the back.

Also, I've made some trays for the top of the toolbox; you can use any combination of 3 small ones, or the one large single tray. Cutouts for 8x3mm magnets are included, but not really needed.
