It’s pretty simple – all 1×3 boards, just screwed together with acrylic glass on top. The trick was cutting the bottom at an angle, so the cans stay inside the divider. And the acrylic glass on the front so I can see exactly how many cans of diced tomatoes I have all the time. I was lazy, so I designed the entire organizer to fit so I wouldn’t have to cut the acrylic glass.
You can use 1x2s and 1x3s instead of the acrylic glass, if that’s your preference. It’ll be cheaper and easier to build this way too. Just screw the 1x2s and 1x3s to the front of the dividers.
I do need to tell you that the canned food organizer that I built was a full 12 cans high – which is super awesome – but dropping the first can in 12 cans high is a little sketchy – will the can blow up? Will it shatter out the front acrylic glass? It hasn’t yet on me, maybe it never will, but just to be safe, for these plans, I adjusted so it’s only 8 cans high.
If you need more can storage, my recommendation is simply to build two (or more) organizers, and stack them up.
