Intro: Universal lamp shade polygon building kitOne 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 thecut-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.

As seen in ReadyMade Magazine, Dec. 2007/Jan 2008 issue

Image Notes1. 30 identical pieces assembled together. this one is made from 0.5mm acetal(delrin). in the photo it looks amber but in reality it is pure white.

Image Notes1. this one uses 24 pieces, made from 0.8mm nylon. it is a bit annoyinglyyellow-ish in reality


Image Notes1. this one has 35 pieces. it is basically a tube with two end-caps. it is made from0.8mm HDPE

Image Notes1. 24 pieces - side view - this one has a 'cool white' light in it rather than 'warmwhite' in the others.

Image Notes1. 80 pieces - side view


Step 1: What you needI 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 theoriginal 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 largerpieces 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 canget 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 togo 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 aseasily). 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 towork 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 shadewith 100 pieces, assuming same size pieces.

Where to get it:

HDPE 1/32" sheet: sheet: http://www.usplastics.com item number 42584

Acetal sheet, 0.015" and 0.020":: http://www.mcmaster.com item number 8738K52 and 8738K53

Step 2: Cut out your piecesYou can cut your pieces in a couple ways:

- trace them out with a marker, then use scissors or a knife. this is slow but can be done easily by anyone.

- make a "cookie cutter" out of sheet metal in the shape of the part. then heat the cutter with a torch and use it to stamp out the parts (only works for plastic)- use a laser cutter

Step 3: Assemble!just try fitting the parts together! they go together in many different ways. you can make a variety of corners with 3, 4 or 5 adjoining pieces.there are several ways to think about and categorize the different types of geometric shapes that can be constructed. below i've shown top and bottom views of everydifferent type of vertex (corner) that can be built. all larger assemblies are made up of a combination of the types of corners shown below, so think of them as yourbuilding blocks.

corners can also be 'left handed' and 'right handed' - mirror images of each other.

Image Notes1. right-handed vertex2. left-handed vertex - the mirror image

Image Notes1. five narrow-angles meet at the vertex (corner) - view of top side

Image Notes1. 3 wide angles at the vertex2. 2 narrow angles and 1 wide angle meet at the vertex3. 3 narrow angles at the vertex4. 1 narrow angle and 2 wide angles at the vertex

Image Notes1. bottom-side view


Image Notes1. 2 narrow and 2 wide angles meet at the vertex, in a checkerboard pattern (the 2narrow-angles are across from each other diagonally)2. 4 narrow angles at vertex3. 3 narrow angles and 1 wide angle at the vertex4. 2 narrow angles and 2 wide angles, with the narrow-angles adjacent to eachother.

Step 4: Assemble!you can make forms with anything from 8 to 100 or more pieces each. the only drawback seems to be that there is no way to make concave corners, only convex cornersare possible.

you can see my examples below, and you can see more at this site: http://www.iqlight.comthat site also sells the parts if you don't want to make them yourself (but i think it is pricey).

Image Notes1. 5 pieces join at this corner2. 3 pieces join at this corner

Image Notes1. this one uses 24 pieces, made from 0.8mm nylon. it is a bit annoyinglyyellow-ish in reality


3. 4 pieces join at this corner

Image Notes1. 30 identical pieces assembled together. this one is made from 0.5mm acetal(delrin). in the photo it looks amber but in reality it is pure white.

Image Notes1. this one has 35 pieces. it is basically a tube with two end-caps. it is madefrom 0.8mm HDPE


Image Notes1. 24 pieces - side view - this one has a 'cool white' light in it rather than 'warmwhite' in the others.

Image Notes1. this is 30 pieces, but in a different configuration than the normal 'soccer ball'shape. it has more pointy corners and less roundedness


Image Notes1. 24 piece - bottom view

Image Notes1. 80 pieces - side view

Image Notes1. this is the bottom central axis point2. 80 pieces - view from about 45 degrees below and to the side


Step 5: Other IdeasI think the design i've presented is my favorite because it is reconfigurable into lots of shapes, but i thought i'd put some links to other styles which can also be made fromsheets of paper or plastic.

the lampshade shown below i spotted hanging from the eaves of a hotel in china. it is made from i think 6 identical pieces (possibly 7 or 8). each piece is a large diamondshape with slots cut in it to allow sliding the pieces together. it looks like each diamond is slid into itself to form one of the central vertical tubes, its free tips are then slidinto the other pieces to hold the whole thing together. (i have not actually made one yet, so please comment if you have).also see:http://www.instructables.com/id/Flower-Calenderhttp://www.yasutomo.com/project/paperlampshade.htmyou can also usually find one or two polygon-inspired lampshade designs at your local designer lighting store, and at Ikea.

si says: Feb 24, 2011. 3:42 PM REPLYIf you don't have the time to cut out the pieces or can't find a nice source, there are now sellers on ebay who you can buy them from, e.g.http://myworld.ebay.com.au/koanliving_aus/

I got some for AUD$17.20 per 30 (delivered price as I sniped 0.99c auctions and negotiated postage with 4 lots). Not as cheap as making them yourself, butthe polycarbonate plastic is good quality, and I'm very pleased with the result.

Looks fantastic, thanks for the instructable!

Chaoz123 says: Jan 26, 2011. 11:27 AM REPLYI've cut out 3 pieces, but I can't figure out how to connect them together. Help please.

wearingpink says: Aug 29, 2008. 9:57 PM REPLYI was thinking of trying to make this. Do you have any idea how big it is?

dan says: Aug 30, 2008. 1:08 AM REPLYit can be any size you want

wearingpink says: Sep 1, 2008. 9:35 AM REPLYI was talking about the red one, and I just wanted an original size to go off of.

dan says: Sep 1, 2008. 11:54 AM REPLYthey were outside a building, probably close to 1m

wearingpink says: Mar 16, 2009. 4:23 PM REPLYSo I made my own version of the red one. It's a little over a foot tall, and made out of mylar. It was a learning process. I'll add a photo when Ifind it.

wearingpink says: Mar 29, 2009. 1:22 PM REPLYOk here's a picture:

wearingpink says: Jan 8, 2011. 10:41 PM REPLYSo I finally made an instructable. Its here!: http://www.instructables.com/id/Modern-Lamp/

CheesesOfNazereth says: Oct 5, 2010. 2:40 AM REPLYVery nice

neonack says: Jan 4, 2010. 7:26 PM REPLYSo do you have your diagram on that? Thats an awesome design.


dan says: Aug 22, 2009. 12:40 AM REPLYooh good work!! was i right about the number of pieces and their shape? i was kind of guessing about it with only the photo to go on (iforgot to look very close at the time i took the photo). how many pieces did you use?

emalcar says: Jul 7, 2009. 3:15 PM REPLYThat is amazing! Nice job! Please post even a general Instructable. I love this!

nabau says: Jul 5, 2009. 3:32 PM REPLYwearingpink...WOW nice work!!! are you going to share your pattern? ;)

infinitysnake says: Apr 16, 2009. 12:11 AM REPLYCan you post some other shots, or a pic of your pattern?

haleysteffen says: Jan 8, 2011. 12:43 PM REPLYI'm attempting the 120 piece light, i cut out all the pieces, and have tried multiple times for hours on end putting it together but it never comes out right andcloses itself off before i can use all the pieces. I understand the concept of putting the 30 piece together no problem. Any help? Thanks.

tangela says: Jan 2, 2011. 12:21 AM REPLYAny idea how this might work with cutouts from poly folders like these ?

hintss says: Dec 2, 2010. 5:24 PM REPLYanyone lasercut it?

draw2blue says: Oct 24, 2010. 10:10 AM REPLYHere's my version made of plain old paper. my first one didn't fit so had to extend it into an oval one, as you probably can it's a bit too heavy to stand on it'sown.. thanks soo much for the template~!

spijk860 says: Oct 8, 2010. 9:40 AM REPLYi saw a men wit those lamps on my holliday in france cool thinges

Klode says: Jun 9, 2009. 1:42 PM REPLYHas anybody tried it with 1/32" birch plywood? I can't seem to find this kind of plastic in Canada and our milk is sold in cartons not jugs... So i am tempted totry it with thin plywood... I am looking to make the 80 piece model... Thanks for your help!

woodNfish says: Oct 4, 2010. 5:55 AM REPLYWhere are you looking for suppliers? Look up industrial supply sources in your area. Worst case you can order over the internet or scavenge otherproducts like kerrym suggests.

kerrym says: Mar 6, 2010. 9:30 PM REPLYI'm in Canada, too. I made mine using those super-flexible plastic cutting mats sold at the dollar store. They come in different colours, but I used theclear/white-ish ones.


tangela says: Sep 30, 2010. 8:42 PM REPLYPlastic cutting mats? The ones that are sold for chopping vegetables on and such?

kerrym says: Oct 1, 2010. 6:41 AM REPLYexactly!

giannacl says: Jun 19, 2010. 4:33 PM REPLYthats beautiful! how many pieces to make that size?

kerrym says: Jun 19, 2010. 6:46 PM REPLYThis one is the 80 piece variation

giannacl says: Jun 19, 2010. 7:39 PM REPLYone more question (blush): what size did you choose?

kerrym says: Jun 23, 2010. 5:23 AM REPLYI just measured them, and each piece is about 5" long and 4 1/4" at its widest point. The finished light is roughly 15" in diameter, 11" high.

giannacl says: Jun 23, 2010. 9:10 AM REPLYthank you!

Ex0 says: Feb 19, 2010. 4:40 PM REPLYI'm in Canada too..I was thinking...would 2 litre pop bottles work?

Moomoomilk says: Jun 21, 2009. 12:22 PM REPLYI LOVE CANADA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


oldschoolstructure says: Jun 19, 2010. 3:05 AM REPLYGreat aesthetic shapes!

cheeto4493 says: Jul 30, 2008. 9:04 AM REPLYCool, I saw this on MAKE and followed the link here.I converted the DFX over into a PDF. I called it IQlight.pdf

I was thinking about the HDPE material you recommended, and I got a thought. How about recycling 1 gallon Milk Jugs?

Shut Up Now says: Nov 26, 2008. 8:53 PM REPLYoh and about how many cds did that particular polygon take

cheeto4493 says: Nov 27, 2008. 4:11 PM REPLY20, plus a few that I broke while cutting and assembling. It is a regular Icosahedron. The hardest part is cutting the CD's without them cracking.And also putting the last one in. I ended up having to break it and tape it back together because it wouldn't flex enough to slide in. The other hardthing about cutting them is making the kerf the same width as the thickness of a CD, and at an angle.

Shut Up Now says: Nov 29, 2008. 2:13 PM REPLYi see.. thanks for the help oh yea i was thinking that it would be cool if after u assembled each set of 5 u microwaved em. if u have ever donethat, it makes lightning and gives a cool cracked effect

mage says: Sep 11, 2008. 9:05 PM REPLYsweet. i really like the cd ball. because its shiny it entertains me :D

frisko says: Sep 11, 2008. 2:16 AM REPLYHey Cheeto, thanks for the cool lamp shade idea!I made the 30 square version as well, and it looks cool...

Does anyone know how to make one of these though?http://www.origamitessellations.com/2006/01/17/identify-me/The cool thing about this lamp shade is that you can open and close every individual compartment...


craftyv says: Jun 1, 2010. 7:20 PM REPLYI agree this is awsome. It is s design called APERTURE by a designer called Claire Norcross and is sold commercially' I too would love to know howto make it .

Alex Ribeiro says: Aug 8, 2008. 8:33 AM REPLYThank you very much for the PDF file version!

KitschyKoo says: Mar 1, 2009. 11:40 PM REPLYThanks for the great idea. I made my one out of some x-rays. I wanted something to hang above our table and as we don't have pendant light, I've just got itsuspended from string. It would look fantastic with a light through it, but I'm happy with it just as a sculptural piece that spins in the breeze. I took the picturewith a cell phone inside it.

craftyv says: Jun 1, 2010. 7:00 PM REPLYKitchykoo: Brilliant use of old X Rays can you imagine how great they would be with a light globe inside and the bones showing through.My next projectis an X Ray lamp for my grandson he will love it, because of the bones.

One point. WHERE CAN I GET XRAYS from as I only have 1 . Help please.
