Rick pointed you to a thread I started when looking for some information on bit holders. There are some really good ideas there on a wide range of styles. I really really liked the idea of the holders from Lee Valley. And would have gone that route except for already having the drawers built with 1/4" bottoms. You haven't gone that far, so these could work for you.
That said, the rubber grommets from McMaster-Carr work great, and are very cheap, price wise. It's a snug fit, but not hard to get the bits in and out of. But that may not work as well if I understand how you want yours set up. Am I right that you want something that is either wall mountable, or a vertical drawer that pulls out of a cabinet so that the bits are tilted a little off vertical...like a display case for router bits? If so, the Lee Valley holders is how I would go. If not, please explain how you want these to store. Jim.
