This is slightly kiltered from topic, but I was gathering enough stuff that it was becoming a problem. I came up with this to hold most all of it:

Varying size and stepped holes for different items (401, 510, 901, 810)

And just for S&G, a couple holders with black walnut inlays in the white oak it is made from.
The hinges are to attach it to the side of the "hutch" on my computer desk. It swings out of the way when not in use.
