/diy/ - Do It Yourself

I have this silly little Altoids tin screwdriver kit that I use a lot at work, but I'm trying to upgrade it a bit. Right now it uses a lot of Wiha double sided bits to save space, and everything is held in place with Kaizen foam. I want to swap them out for normal bits, get a few more sizes and types of bits, a couple of sockets, and a bit holder for an extension. I want to keep all that in this little tin(and maybe find a slightly bigger tin) without it rattling all around though. Right now the best option I can come up with is to put a couple strong magnets on the edges to cut down on movement, and then put some silicone to dampen the noise when it does move. I just wanted to bounce the idea off of you guys to see if you had better ideas(or knew where to buy better tins) before I buy the magnets.

I carry this little Altoids tin sized screwdriver set at work, and it's come in rediculously handy. I'm upgrading it, and making a similar one for someone else. I'm thinking one big but thin magnet on the bottom, or maybe a couple on edges, under the lip, and then coat the inside with something to keep what little rattle the magnets don't stop from making too much noise. You guys got any suggestions for what to coat it with?
