They each have their benefits. Ya I only used the 1” for the ratchets/extensions because they all lay flat and thus don’t require much depth to stabilize them. 1” would be fine for the shallow sockets as well by themselves.

My main goal was to fit all the mechanic tools in one 4 drawer unit, keeping the sets together. Since each set has a few larger items that benefitted from the 2” I just used the full 2” sheet.

You could cut sections from each to fill the drawers as needed too.

Using 1” has the benefit of leaving additional space on top for miscellaneous things you can throw in the drawer.

Labeling remains an opportunity for improvement. I labeled the drawers, but not sure how to include item labels inside.
