Hi there,
So get your organization on the Grid 
The tool is here,
For any bin size you want or custom grid…go here,
Layout what you want and pick the shape and tolerance as well as the finger holes (for removing it) works so well Who needs sleep.
Shrink it or Grow it, Scale it to whatever. Add the Grid of your choice to the Back or the Tool or outline of your choice.
Also worth noting: grid systems exist for all major toolboxes and storage containers. Harbor Freight, Sortimo, DeWalt, Milwaukee, and most big-box store units have replacement or custom bins available.
It’s a great time to buy a 3D printer if your into making your own enclosures, panels, holders and other useful things and IF you can READ 
then you can do it. They pretty much just work, not like it used to be. No tweaking 
required, finally out of the box printing. Multicolor if you have the Leg 
(I switched rolls manually for a good while) 
When I complete the Setup for the tool drawers I’ll post thos e finished pic’s
Enjoy.
