Beer Bottle Shelves

My brother has a eccentric collection of beer bottles that grows with every unique beer he tries at home. He was looking for a way to maximize the display of bottles while still showing the bottle labels instead of just storing them in boxes. To add to the challenge, beer bottles come in a couple different sizes in addition to the cans in his collection. I came up with a design and mocked it up to see how it would work. After getting approval, I made 6 units with shelves for the entire height (holding ~120 bottles) and 2 with shelves half way up with adjustable sections on top for the very odd shaped bottles (holding ~80 bottles depending on shelf positions). The units are sized around the Ikea Billy shelf system, so that doors or other units could be added in the future.
