Necessity is the mother of invention. You're the father. And all those accessories are the children. (Ok, so this is a stupid post, but I had to write something about your handiwork. Looks good.)
Wow, I REALLY like this project… There is just something satisfying in making something functional for yourself that you can appreciate without worrying about what other people will think about the wood, joinery, finish, etc. I also agree with what Charlie said. You've managed to put style into something that most people would just hack because it's only a drill bit case. It just shows that it doesn't have to be all or nothing (all dovetails and French polish or no style/effort).
I agree with Doug - making stuff for the shop is a fun way to explore new territory. I just made a thin rip jig and learned a few things along the way.
