Id make your own storage solutions instead of basing it just on what they come with. Most factory trays are bulky and flimsy anyways.
I use both Ernst and snap on wrench racks. The Ernst ones are made for the size of the wrench the snap on are not. Both have their advantage.
I use the plastic socket rails that every body and their brother rebrands and sells for my sockets.
Ernst makes some nice low profile screwdriver racks. I have a set of them. For the rest of my drivers I just plan to find some form of L or T shaped material (like drawer dividers) that I can stick to my drawers and cut slots in them for my drivers. Then it's setup the way I want it and tailored to my drivers, not at the mercy of a factory tray. Some people feel the best organization for screwdrivers is a full drawer lol.
You can also get drawer dividers for little parts.
As I mentioned in the Knipex thread, just laying pliers out and tight works best for me, let's you fit a lot of them in. I suggest shadowing them though if you can.
Plastic socket rails. I had been using factory storage for a lot of them and Hansen trays in the big drawer. I was able to get back two drawers and still have extra space by ditching the OEM storage.
Here's an example of how much space the factory cases can take up. These are all in my top drawer now and I have room for more tools.
Wrenches as I was part way through reorganizing. The wrench racks keep the wenches very tight to save on space and allow you to set things up however you want. I put some acrylic foam tape on the base of them to keep them in place.
Ernst low pro screwdriver rails.
My pliers solution is low tech, just fill the drawer lol. When I swap the liner for the pig mat adhesive liner I'm using in my other drawers I will shadow the pliers so I can tell if one is missing.
With all of that said, I do realize it takes more work and time to do it my way. I go for maximum tools per square inch, others do not. Some factory cases are not bad. I certainly wouldn't miss out on a deal or higher quality tool just because of the case though but that is just my own opinion. Worth what you paid for it lol.
