Obviously, these don't work if you have large amount of stuff, or large bottles. Well, one of these works for a lot of stuff, except large bottles.
Plano mini-magnum -- a quick web search found them at Sportsman's Guide, so they're still around, and I found a variation on the theme at TackleDirect. The dividers aren't movable. The flip side has 5 full-width compartments.
This is a parts / fastener organizer I found at Home Depot. Couldn't find it on their website, but I think I saw them at the store last I was there. Adjustable dividers and lots of room.
This is a bit box from DeWalt. Very handy 2-sided clamshell box. I like it for driver bits because the sides have locking covers. Nothing spills when you open it. Has adjustable dividers.
