Late getting back to the game...
Here's the $5 solution like was mentioned earlier. I had some extra foam rubber floor matting. The kind you use in a home gym, or what not (what I used it for). It interlocks along the edges, super cheap, know what I'm talking about? (Edit: I just realized there are some pieces sitting next to the box in the first picture, so you know what I'm talking about.)
Cut out the dimensions of my drawer on it with a box cutter, laid out the tools, traced them with a sharpie, and cut them out with a dremel. You'll see a few of them have little chunks missing... I was experimenting with different dremel bits. Hands down the best thing to use was a regular wood drill bit. Just make sure you have something under it you dont mind scratching up. My next drawer will look better now that I have the technique down.
Did the same thing for wrenches too.
Socket set I have a set I've been using on my cars for years. Cut it in half and the halves laid into the drawers perfectly.
Yes that's a couch next to my tool box, I have a couch in my garage.
