Cardboard Kitchen Cupboard Organizer

Intro: Cardboard Kitchen Cupboard Organizer

Ever since we moved into our apartment, we've had a kitchen cupboard stuffed full of all the odds and ends that wouldn't fit anywhere else. I always wanted to tackle this mess, but frankly kept putting it off. Once I finally worked up the motivation to start, I decided to use cardboard to create an organizer as I thought perhaps it would make the construction easier and quicker. As it turns out, cardboard isn't as easy to work with as I thought, but I was still able to accomplish what I set out to do. Let's get started.

STEP 1: What I Used

The materials for this build are very limited:

Cardboard (I picked up from the dumpster)

Glue (I used Elmer's wood glue, but lots of glues would work)

Wood Filler

Spray Paint

The tools needed are also quite simple:

Ruler

Knives (X-Acto, utility knife, and/or razor blade)

Bending Brake (Ok, so this is totally unnecessary, but I had one that I just made)

Heavy Duty Paper Cutter (Also not necessary, but saved some time)

Small Clamps

Heavy Books

Trough for Wood Filler

Sand Paper

STEP 2: Remove Stuff and Organize

The first step was to remove all of the stuff from the cabinet and organize it. This allowed me to easily see what I was working with and also get an idea of how many compartments I would need in the finished organizer.

STEP 3: Measure Everything

Next everything was measured. This included the space into which the organizer needed to fit as well as getting general sizes of the stuff being organized. As I continued in the design, I had to re-measure and re-organize the stuff to ensure that it would all fit into the organizing slots being prepared.

STEP 4: Design

I designed the organizer in Sketchup, which made it easy to ensure that everything worked out in 3D. It was designed around 1/8" thick corrugated cardboard that I picked up in the dumpster. I've attached the Sketchup file if you want to take a more in depth look at the design.

STEP 5: Design Elements

Rather than going in depth into the design, I think it's more beneficial to point out several design elements that I used for joining the pieces of cardboard together. First, I decided to double up the cardboard for the entire structure, which added significant strength to the design.

Since the weak points of this structure would be the 90° joints between the pieces, I decided to recess all of the joints. In the figures above you can get an idea of the three types of joints I used. The double layer recess joint is the preferred joint, unless there was some other design constraint dictating that the single layer joint be used. The staggered recess joint was only used at one location, where joints needed to be made on both sides of a single vertical support.

Long pieces of cardboard were bent to form the outside of the organizer as this prevented joints at the corners, which would only have been supported on one side. I'm sure there are better ways of joining up cardboard, but this is what I came up with off the top of my head.

STEP 6: Convert the 3D Design to 2D

I carefully worked through my 3D Sketchup design and converted it into a 2D drawing of all of the cardboard pieces needing to be cut and/or bent. I used CorelDraw to generate this 2D drawing, which was simply printed and used as a reference as I cut out the pieces.

STEP 7: Cut Cardboard

All of the cardboard pieces were marked and cut using several different methods. For straight cuts less than 12" in length, I was able to use a heavy-duty paper cutter, which surprisingly made a pretty decent quick cut. For longer cuts, and those that were more intricate, I used a combination of a razor and/or utility knife. The trickiest cuts were the curved bits for the rolling pin holder, but these were easily made using an X-Acto knife.

STEP 8: Bending

Several pieces needed to be bent. I used my sheet metal bending brake for this. I'll admit this is a bit overkill, and you could accomplish the same thing by bending around the edge of a table, but I just made the brake and it actually worked really well in making nice square bends in the cardboard.

STEP 9: Start the Glue Up

I used Elmer's wood glue to glue everything together as it's what I had on hand. I wish I had used something that would've set up a bit quicker, but Elmer's glue isn't bad as you only need to clamp the pieces for a half hour.

I started the glue up at the bottom corners of the organizer and slowly worked upwards and inwards throughout the following steps. The exact order you take isn't terribly important so long as you can still assemble everything as you go along.

STEP 10: Continue the Glue Up

I gluing up the bottom and sides of the organizer. The center support was added, followed by the lower level support and shelf located to the left of the center support. Next, the vertical supports and shelf to the right of the center were fitted.

STEP 11: Finish the Glue Up

With all of the vertical supports fitted, the wide upper shelf was glued in place, followed by the top piece of the organizer. For the shelf and top, small clamps were used in addition to the books to help hold everything together as the glue set up. Note that these clamps aren't really tightened down as they would crush the cardboard. I simply tightened them to the point where the two pieces of cardboard were in contact with one another.

STEP 12: Seal Front Edge

To give the organizer a more finished look, I sealed the front edge with wood filler. This actually took quite a bit of wood filler as I had to fill in a lot of corrugations.

STEP 13: Final Finishing

Once the wood filler set up, I sanded it smooth with 320 grit sandpaper and painted the entire organizer with white spray paint. I wasn't quite sure how spray paint would work on cardboard, and I was a bit disappointed with the result. Cardboard really soaks up the paint, which meant I had to apply a liberal amount of paint. I ended up using the entire can on the organizer and the coverage was barely sufficient. It may have been better to paint with a brush, but I'm assuming this is just one of the drawbacks inherent to finishing cardboard.

STEP 14: Organize

The final step was to put everything to be organized into it's slots and enjoy my newly organized cabinet.

For the most part I am pleased with how this project came out, but there are several changes I would make if I were to do it again. While using cardboard was an interesting experiment, and it worked out from a structural standpoint (the organizer is super solid), it comes with two drawbacks. First, I found that cutting, bending, and gluing the cardboard wasn't as easy, quick, or accurate as I hoped it to be. I imagine that some of these issues could be resolved by better techniques, but for the amount of work and time spent I feel like I should have just used 1/4" plywood. Second, as I mentioned previously, painting the cardboard proved to be problematic. In some ways I preferred the unfinished cardboard to the painted cardboard. You expect cardboard to not look perfect, but adding paint to it requires that it look like something better than cardboard, which it really doesn't.

Despite these misgivings in the finished product, I'm still happy with my newly organized cabinet and learned a lot from this project.

Really awesome project! The production quality of the video is really great!

[JoshXarles]

Thanks! I'm glad you appreciated it :-)

I have to admit, english is not my native language, and when I first saw the first picture I said "no, probably cardboard is not what I think" because... Well, it doesn't look like cardboard anymore. It seems much more solid and professional. Very good job! And thanks for sharing

[JoshXarles]

Thanks! I was hoping it would be even a bit more professional, but it was my first cardboard project so I'm happy with it.

[sesshuswan]

might help to prime it with a mix of glue and water before painting so the paint doesn't soak in

[JoshXarles]

Not a bad idea. Thanks!

[ImiC]

A great examples of recycling things :)

[JoshXarles]

Thanks. Using what you have on hand is always the best I think.

[LilacLisa]

I soooooo need this in my life! Thanx!!! :)

[JoshXarles]

Haha. I'm glad you like it :-)

[EM3Di]

very very good! awesome!

[JoshXarles]

Thanks!

I thought it was white foam core board at first (which is expensive.) It looks very sturdy and congrats for using something from the trash!

[JoshXarles]

Thanks! It is surprisingly sturdy, which is what I was going for. If I had a thicker cardboard I probably could have got away with 1 layer as I'm not sitting on this or anything.

[aliasak]

looks very nice! I also did something similar with foamcore. We have a cupboard filled with various water bottles and acrylic cups (like from Starbucks) and it was hard to reach for things in the back. I made this so that each one is accessible without having to take out the ones in front or knock them over. Additionally, it was a good time to also donate the ones we rarely use :-)

So far it's been working well, but I wouldn't place super heavy items in the slots. The panels are assembled by cutting slots halfway through and then sliding them together. Like makjosher, to do it again, I would use 1/4" plywood next time.

[JoshXarles]

That is a really great solution for you problem! I'm sure it was much easier to make than mine :-) We too have a few things to donate from our cupboard.

[Swansong]

This is a great way to save shelf space! The store bought organizers add up quick and aren't as adjustable in design. :)

[JoshXarles]

I'm glad you like it :-) I did need something more versatile. Still, I had to work it carefully to make sure everything fit.
