This is a project I was helping someone get finished. I designed if from a rough sketch and it holds 15 standard Penzey's bottles. I like it and think I will be making a few of them. This one is from aromatic cedar, but I would make it from anything you like.
This bad boy smells so nice I don't think I will seal it.
Still needs sanding and gluing and is just rough fit now.
This fits in a 12x12x12 inch foot print.
Every panel is CNC machined
I could also design one for you based on your guidelines
More bottles, less bottles, bigger bottles,
If something like this interests you drop me a note and I will get one together for you.
