Nice project, but it does assume one product per column, and that all cans are a standard size. Maybe a solution for the canned goods you use most frequently...
Maybe a mechanical engineer could answer this with confidence...<p>Since one of the stated purposes is to "rotate" (FIFO) the stock of cans, if you use the 18-inch tall plexiglass front, what's the risk of damaging the cans when dropping them down?<p>If there's even approx. 1/8 inch left-to-right wiggle room, it seems a can lid edge can strike the side of another can near its lid edge. Can this unseal? If so, how visible would it be?
Doesn't the plastic from the can liner leaches out into the food. Presumably the longer you keep it the more it would leach out. I usually go for glass containers for this reason. On the other hand if the nukes go flying, having a can organizer of luxury campbell soups could be a life saver.
My local supermarket (in Japan) sells canned soup in a rack like this. It's a bit looser and the cans come out horizontally at the bottom and hit a stopper, so you grab one from the top rather than the sides. The one in the article is more compact.
