I've had so many requests for where to get the Tool Tower that is described in the post from August 20th, that I finally went through my files and tried to track it down. As best as I can tell, this company - "Think Inside the Box" has gone out of business. However, I believe there are similar things at stores that specialize is in organizing you home. I did find a cosmetic organizer on line at Storables that looks like it might work. It doesn't have the graduated bottom which is really nice, but it might get the job done. - Here's a link to it.

If anyone else finds or uses something better please let me know so I can share it with everyone. Thanks!!
