Tried to figure out some wall storage. Here’s what I came up with. It works pretty well. The spacing isn’t perfect, so some of the cigar boxes are a little tight. You just have wiggle them a little. :)
I cut grooves in the board that’s attached to the wall measured to just fit each cigar box plus the support thickness. Each support piece is held with glue and screws. The whole unit is then screwed to the wall.
