This is a drop in modular drawer system for the Kobalt Mini Toolbox, the insert sits flush with the top drawer but also sits nicely in the bottom (larger) drawer as well. 

The drawer has three vertical and horizontal dovetail cutouts that run on all four sides that allow for the dividers to simply slide in or be removed. The inserts themselves were designed to have a slight offset that allows for them to both sit snug but also be removed with ease. 

The dividers can be done as basic as three running either horizontal or vertical. But then there are also sub-dividers that allow for dozens of possible combinations. Dividers labeled as double dovetail are ones that have dovetails on both sides allowing for more sub divisions to be made. Dividers labeled as single dovetail only have the dovetail on one side. 

The dividers can be flipped or reversed once printed allowing for any orientation you choose. The pictures attached show just some of the possible combinations with plenty more still imaginable!

If there are any dividers or combinations I may have missed please leave a comment and I will work on getting them up! Also working on a drawer insert that sits flush with the top of the larger drawer.
