Cardboard might seem like an odd material for a desk lamp, but with a low-heat LED bulb this 15" lamp can shine all night in glorious maker style. It's light, it's sturdy and it's flat-pack. What's not to love?

I originally designed this lamp to go on my own desk in the Instructables Lab, but due to popular demand I've had to make a few more. It's now available on the Instructables Store. I hope you like it!

I designed the lamp using Autodesk 123D and Autodesk 123D Make, then cut the parts using a laser cutter.

Here's how it all fits together:

Step 1: Designing the lamp model

I started by designing a 3D model of the lamp using Autodesk 123D, which is freely available online.

To make a cross section of the lampshade, I used the Draw tool and the 3-Point Arc tool. Notice the grooves on the inside of the lamp; they're carefully sized to hold the electrical lamp components in place once the lamp is assembled. Everything else was just roughly estimated and tweaked as needed.

To turn the cross section into a 3D object, I used the Revolve tool. This tool spins a profile around an axis of your choice, producing an object with rotational symmetry.

I made the stand using a combination of hand-drawn splines and hemispheres, adjusting it until it looked sufficiently lampy. At the time of writing, Autodesk has not yet included a tool for accurately measuring the lampiness of a 3D model, so I had to judge that entirely by eye.

I joined the two parts together using the Combine tool (set to Join mode), then exported the object as an STL file.

How thick is the cardboard you used?

AzzysDesignWorks made it!3 months ago

Did one up the other day. came out looking great. Had to make a few changed during assembly because of the socket my home depot had availible had a different clamping setup and differnt profile.

And I would recommend using a spot LED instead of a stanard edison type bulb, too much light escapes the sides making this lamp hard to look at.

I downloaded your eps files and just wanted to verify one thing. The eps with the single part in it (part 0) is not on top of the "canvas" in the file. I'm assuming that makes no difference when attempting to print?

Beautiful, but.....can you say fire hazard? I knew you could!

A fair point. As I mentioned in Step 6, this has only been tested with low-heat LED bulbs. I suspect that using it with a normal bulb would lead to... interesting lighting effects.
Indeed. Needless to point out, but there are a certain number of people who lack the ability to read directions....or warning labels, either, for that matter. I'm just doing my part to keep those folks from burning down their homes.
survival of the fittest?
if they lack the ability to read directions...they lack the ability to read your part!!!

Dear friend

Anybody can advise the setting for use laser cut the cardboard?
(I don't want to bern the machine)

Thank in advance
Best regards

Depends on the power of the laser. Low power and fast speed should be fine. I use a 100 watt laser so it cuts 4mm MDF with ease on a fairly quick setting 350cm/min on circa 50% power.

Saw this and though, AWESOME! Have acess to a SEI Mercury laser running ICARO software so thought I'd give it a go. The software opened the .eps file no problems. I deleted all the numbers (reckon I can figure the assembly out without them) and made sure all the layers and laser settings were okay. I cut the lot in one go out of 4mm mdf which the laser managed with ease. Not assembled it yet but tried a few pieces and the fit is great with the 4mm. Just need to find the right type of lamp fitting here in the UK now and I'm sorted. Many thanks for the files.
One minor point though, a DXF file would be great as it can be edited and re-nested at the desk as opposed to on the machine. Just a minor point.
wow ,really ,good designed ,i admire your intelegent!
Actually......

If I were you.......

I'd be making this out of something far better, like plywood....

Because it's so good it deserves to be made from something durable.

With some good PVA glue, it would be very strong as well.
Files seem to open only in newer versions of Illustrator (I am using CS3). Please add alternative, more universal formats. I think this interesting project will benefit from these additions.

This lamp is great! - I loved it! - I bought it!!

The store doesn't have a place for reviews, so I'll review it here: There were no instructions included: What you see here is what you get. That was enough to 'get er done', but maybe some insider insight would have produced a better build. As it was, the laser burned part numbers/markings were cryptic and a fair number of joints had to be forced. All well and good when I'm making stuff out of old boxes, less cool when I paid for a laser cut kit. Sorry to rant, but not sorry enough to quit... The packing method used (Cling wrap a pile of cardboard pieces to one big pice, throw a heavy lamp unit on top) ensured numerous parts were bent. Lastly, QA was asleep: I received two #7 discs, and no #8 disc.

So maybe a store is not a good idea.

Happy Valentines!!

Hi,

I have been trying to get help with 123D-Make. Everytime I try to import a file, the software just crashes. I tried different OBJ files. Have you run into that trouble? Any idea what I am doing wrong?

O.О That was just great!
nrune2 years ago
Sold out! Oh man! Would you make one more for me?? Don't have a laser cutter, great office conversation piece. Let me know.
whitefink2 years ago
this is a fine project, i've had problems with the .net 4 framework requirement, really slowed down my poor old surplus computer, also autodesk123 left out
some of the best line tools from older autocad.

Awesome! I am also wondering that would collect so much dust? or NOT? Thanks for sharing!

EPS not opening, cAN U PLEASE UPLOAD dxf INSTEAD
Yes please I vote for DXF's as well my cutter doesn't understand EPS's .....OR does anyone know of software that can open EPS's and save as DXF's ......I can't find one!
Pls hepls include the EPS file with all of the cut-out pieces!

I've just added it to Step 2. I can't wait to see your finished version!

Definitely post your design files on thingiverse.com so other people can make this same lamp! Sharing is caring.
PenfoldPlant (author)  natantus2 years ago
Sorry about the delay! The EPS files are now up available here in Step 2.

Would be glad if if could upload the EPS or DXF file...Thanx in Advance
wow grest! very nise desing...

Is there any reason this could not be made out of laser cut plywood by a service like Pokono?
BrianJewett2 years ago
This would be even cooler in Coroplast! You could even mix different colors.

www.coroplast.com
I thought the same thing, but I have never heard of anyone cutting coroplast with a laser cutter. First of all you would need to use a dark color to allow it to absorb enough heat to burn/melt, and then you have the problem of it just flowing back together after the cutter has moved on.

I think a CNC router or maybe a CNC controlled knife would work better.
Ooh, not bad. There's also a bunch of the stuff around every time there's an election.
Is there any way you could email me the demisions? i dont have a laser cutter or that software so i have to cut if by hand
PenfoldPlant (author)  bob_da_builder2 years ago
D'oh! I forgot to include the EPS file with all of the cut-out pieces! I'll have these posted within the next couple of hours, so check back soon!
Hey. I really loved your lamp. I was just wondering if you can put the file for download. Because i would like to give this as a gift to my best friend.
Thanks in advance :)
