I had this done for a customer who wanted a case for her collection of shot glasses. Each cell had to be 4″w x 4d” but the height was designed to have variable heights based on a sketch up. It’s actually 5 feet long.
The 1″ thick case sides were made of maple, the inside was 1/2″ thick plywood with maple edge banding. Back panel was 1/4″ birch plywood.
I have to say I underestimated the work involved with this one. One small error in any dimension through each cell off exponentially and it’s easy to see these lines stray off square.
I had to redo it a couple times before I found a solid work flow.
I took it as a learning experience.
