If you want to do foam inserts, that stuff is called Kaizen Foam. Buy it cheap on amazon, lay out the tools you want, and cut out layers of the multi-layer foam to get your tools to sit in there. Obviously this also allows you to customize the shape of the tool holder to your drawer. It's cheaper than buying pre-cut inserts, and as a bonus, you can make it specific to your tools.

I think I’ll get some of that for home I’ll be able to compare it VS the ones of grainger, ordered those through work since they were nice enough to buy them.
