Damonfg, over here in the UK we have square plastic (PVC or ABS) electrial trunking in all sorts of sizes and it's cheap, rip it in to channels on a table saw, often you'll get 2ft out of 1 if you get my drift.
Just lay them in the drawers, and they can easily be taken out for cleaning,..... that's if you do that sort of thing.
Another idea, cut rebates in say 1X2 and lay them side by side, or even thin ally extrusions....... MDF or whatever you call it, and mill slots in boards cut to fit snugly in the drawers,..... ball end if you want to go posh.
We have kitchen type plastic cutlery drainer and storage trays? they're both tough and cheap.... for the bigger stuff. Your WallMart must have those, surely.
Anyway, keep you a troshin bor. Sami.
