Instructables
One simple cut-out shape lets you build all sorts of different designer-looking lampshades! You can make dozens different geometric forms using various numbers of the cut-out shape made from paper or plastic. All the standard mathematical polyhedrons and such are possible.

The pieces just fold together by hand into rigid forms, and you can take them apart and build into new shapes any time!

this is fun and educational for kids and adults alike, and you get a really nice lampshade when you are done.

Step 1: What you need

I saw a lampshade made out of the shape below at a friend's house, so I traced the shape and made my own. the lamp i saw used thin plastic for the pieces. I believe the original design for this lamp was done over 30 years ago by the firm Iqlight, they sell pre-cut parts in case you do not want to make the parts yourself.

Below is the shape as an image, and i've also attached a DXF file.

You will need sheets of paper or plastic that allow light to get through. The stiffness of your material determines how large your pieces can be - stiffer material for larger pieces and larger lamps, thinner material for smaller pieces and smaller lamps. (see next step)

You will need a lamp fixture - just a raw socket on a cord. I found some nice ones at Ikea for $4, and some fluorescent bulbs. Use a compact fluorescent bulb so you can get more light without melting the plastic.

I experimented with a number of different plastics and sizes for the parts, here are my results:

- HDPE: works well, looks good, cheap and easy to get. I used 0.8mm thick stock for 8cm pieces (measured flat-side to flat-side). That's about the smallest you'd want to go with that thickness, you could go up to 12 or 15cm with that thickness. this is the least expensive plastic by far. One of the commenters suggested using plastic milk-bottles, which are made of HDPE, this is a good idea!

- Acetal (delrin): this seems to be the best choice for looks, it has the purest white color and best light dispersion (basically, looks just like acrylic except it doesn't crack as easily). I used 0.35mm stock for 6cm and 8cm pieces, and 0.5mm stock for 8-12cm pieces, and 0.65mm stock for 12-15cm pieces. It still is a little brittle and harder to work with than HDPE, and more expensive. if you cut this with scissors it will be somewhat tricky due to the brittleness, but possible.

- Vinyl: I did not try it, probably want to use thicker pieces since it is not very stiff. but you can use colors!

- Paper: I did not try paper but it should be good for smaller constructions.

- Laminated paper: this is a great idea suggested in the coments section. try laminating color tissue paper, then cut the pieces from that. very unique and colorful!

- Acrylic: too brittle, it will crack when you try to assemble. too bad!

- Nylon: has a yellow-ish look when lit up which makes it undesirable.

- for a large construction use stiffer material for the same size piece. ie, if you are making a lampshade with 12 pieces use thinner material than if you are making a shade with 100 pieces, assuming same size pieces.

keep all of the tiles oriented in the same direction when locking them together. this one is made of plastic from milk jugs. use WD-40 to remove the adhesive labels from the milk jugs.

Hello, I really like your lamp and thank you for sharing all the information.

I have a question for material you used.

Did you use laser cut for HDPE and delrin? if so, then where did you do?

Thank you.

I need to refix a universal lamp shade I have and your not helping much by not giving me the instructions to put it back together after we put a new light in it.

can you buy the pieces for this project pre cut? If so, where and what are they called?

I made several of these years ago when I first saw the on this site, in fact as I turn my head to the right I can see two that Ive kept because I love them so much. Iv'e made them from paper, plastic and even place mats. If the main point of your Instructable is to laser cut your pieces I entirely agree unfortunately I have no money or tech skills so it's hand cutting for me.

Could you use milk gallon jugs? Would the plastic be thick enough?

Super cute! What material did you use to get the different colored and patterned pieces?
Muito legal. Amei.
Love Love Love this lamp! What do you use to cut it out of plastic? and do you start at the top or the bottom?

Thank you so much for this. My boys saw some guy selling kits to make these at our fair this year. I thought they could make it themselves so we didn't get it. Now I have a template and instruction so I can make them a kit for Christmas!
My version upon this tutorial made with beer cans, with labels facing inwards. It gives the shade a crisp aluminium look. Cutting the template out from each can was a killer, but the result was worth.

How many shapes did it take to make the complete sphere?
30 pieces.
This is SUPER!!
Thanks!
This is cool! You could always pre-punch holes in the metal before assembling if you want light to come thru but I love it as a metal sculpture!
Thank you! And yes, I could do that.

So did this guy steal this from you or what Dan?
dan (author)  artanis2 years ago
what's old is new again! you can't steal a free idea.

i think if you are here at instructables you are more interested in cutting out your own pieces from an interesting material than paying someone else to do it for you.

can someone please help me out on how to make the HUGE ball with 120 modules? I keep ending up with 30 module ones....
dan (author)  knutmo7 years ago
i've added some more photos in the last step including an 80-piece construction which is built very similar to the 120-piece one
knutmo dan7 years ago
thanks for the extra photos, but I still can't seem to do it. I really fail to see the patterns in your examples and in the few drawings I have found. I'm able to make the 30-piece balls when I follow the steps and the video that's on the IQLight website, but I have nowhere found similar instructions for the bigger ones. If someone has step-by-step instructions I'd be really grateful!!!
First of all, thanks Dan for this great instructable. I've had a lot of fun building this things. As a small contribution, I created a "roadmap" for the 120-piece one. I painted the pieces with two colors, to distinguish between the two faces (some pieces go face-up, and some go face-down). I also added a view of the bottom part to make the beginning a little easier. I built a 14cm diam. version with paper (this is how I understood the structure). As you can see in the pictures, it looks more like a dodecahedron rather than a sphere. .

Hi, thanks so much for this. Have just bought 120 pieces in Thailand. Sorry to be thick but can you tell me - do you make each of the top elements first (as my instruction sheet, then add the long row, then the next long row and then the bottom elements. Hope that makes sense, what I'm asking is what order did you put this together in. thanks
Hi Starcana!

The way you describe it is pretty much correct, except for the fact that it is a lot easier if you take the bottom element as a start. You have to assemble the first five pieces (the white ones in my diagram) forming the pentagonal base, and then you continue growing that bowl-like structure row by row (adding "circles"), until you get to the closing phase, where you'll eventually end up with the last five top pieces, that you'll just have to interlock.

It may look complicated, but you'll se that once you've done the first couple of rows it's pretty straightforward. Just keep an eye of the orientation of each piece.

Happy building!
Thanks for this but I'd given up and have just completed the 60 piece one which is probably a better size for where I want it. Just the flex/bulb to get in now without it collapsing! Thanks again.
i did it! i finally did it! thanks nevermore. i couldn't have done it without your help :) i made mine with HDPE plastic from plastic bottles :)
Hi! I used regular printer paper, it's OK for that size. The pieces I used are 4.5 cm in its long diagonal. They're quite small, so be patient with the scissors.... Using those numbers you'll be able to predict the final size of the ball. Have fun!
amazing! what kind of paper did you use? im afraid normal printer paper will be too flimsy. also, what was the approximate length of pieces that made a 14cm ball? id like to to be able to predict what size it comes out to.
thank you SO VERY VERY VERY MUCH for your excellent roadmap!! This is exactly what I needed to build my 120-piece behemoth lamp! I couldn't have done it without you guys!!! If you're ever in Utrecht, The Netherlands, be sure to look me up and I'll buy you beer.
