Geometric Cardboard Lamp

FeaturedContest Winner

One of the things you may notice from all of my projects is probably my love for cardboard and lamps :)
My new creation mixes both these things, so working on it was really fun! I made some mistakes at first, and that made the work even longer, but they actually opened up my mind on new ideas that can be made with this technique.

This lamp is a dodecahedron composed by many pentagons that have been joined together. Composing it isn't as hard as it may seem, I must warn you though, that you'll need a lot of patience and time to cut all of these pieces by hand!
Don't worry, the result will reward you, believe me! ;)

The Featured Author Contest is what pushed me to make this lamp, and I've come to realize how much I missed creating lamps! Thank you for this opportunity Tarun Upadhyaya! :)

Step 1: What you need

  • Cardboard - I used a thin one because it was easier to cut by hand
  • cutter
  • ruler and pencil
  • hot glue
  • white glue
  • LED* light bulb and bulb holder

*the LED light bulb is very important because it won't burn the cardboard.

Step 2: Draw the pentagons

Picture of Draw the pentagons

Draw 11 regular pentagons on your cardboard. In case you don't know, a regular pentagon is a pentagon that has equal sides.
The sides of the pentagons I made are 6cm long (2.36 inches) but this is up to you anyway. The most important thing is that all the pentagons must be equal. Try to be as accurate as possible!

In case you don't remember how to draw a perfect pentagon (I didn't), take a look at this video.
I first drew it on a piece of cardstock, cut it, and drew its outline on the cardboard multiple times. Drawing them was much faster this way.

For those who don't know Linda and I won our first ever contest by making a cardboard lamp. Since then I have become a huge fan of Linda and her cardboard creations never ceases to amaze me. She is my all time inspiration source.

With this amazing & creative lamp, I respect you even more. Thank you for being so awesome and an everlasting source of inspiration and a dear friend :)

Tarun, I can't thank you enough for this, really. It means so much to me!
And I can't tell you enough how honored I am to know that such a great artist thinks all of these things about my work. You know what? I'm extremely proud to call that artist FRIEND! :)

I know for sure that all the things I make are inspired by something, sometimes I can't realize right away what actually inspired me, but every time it comes back to me and believe me, your creations are always a big part of it.

Thank you, thank you, thank you! :)

To make my version, I cut 7" pentagons out of black foam core, and then cut 6", 5", 4", 3" and 2" pentagons out of the 7" ones. I used hot glue to put the whole thing together, and it came out great! Thanks so much, I can't wait to try it with other shapes!

lindarose92 (author)  ExtraordinaryAz7 days ago

That sounds great! I must try foam core as well, it must be so much easier to cut than cardboard :D Doesn't it melt using hot glue by the way?

Please share a picture of it if you can, I'd love to see it! :)

I promise that as soon as I take pictures I will post so you and everyone else can see how awesome it turned out. As for the hot glue, it doesn't melt the foam core and is actually the only thing I've been able to find that will reliably bind pieces together. For some reason, the stuff just doesn't take well to adhesives! Next time, I'm going to try black glue sticks. (I used black foam core!) I think it will look even better. Thanks again!

Wow, this is great!! I love the fact that you kept the central part of each pentagon. While I was making mine I couldn't make up my mind whether to keep it or not and I finally left the central part free. I think I will keep it next time, I really like the way yours turned out :)

Hey Linda, This is an awesome lamp. Really love your work. Especially the lamps. They are en-lightening :) You're a rock star and newbies here including me have a lot to learn from you. Thanks for all the Ibles. 74!! Amazing.

lindarose92 (author)  hardlydavidson21 days ago

Oh that is so very nice of you, thank you so much! What you said means a lot to me :)
I have just seen your lamp and, believe me, I have many things to learn from you as well! I can't believe I missed it, you did such a great job!
Looking forward to seeing more ibles from you :)

Nice 'ible. I have some 7/32" luaun underlayment leftover from another project. Think I'll try using it in place of cardboard.

lindarose92 (author)  pattiemelt23 days ago

That's a great idea! Let me know how it turns out and please post a photo of it if you can :) I would love to see it!

rabbit_man28 days ago

I may have to try my hand at laser cutting this.

lindarose92 (author)  rabbit_man28 days ago

That would definitely be much easier and accurate :) Let me know how it turns out!

kserwin29 days ago

Absolutely beautiful. You could get lost in the light and shadow effects it leaves on whatever is around the lamp. I have a box of cardboard scraps (I use it for armature and patterns for paper mache sculptures), so I'm going to give it a try.

lindarose92 (author)  kserwin29 days ago

Yay I'm so happy about that! Thank you! Please share a photo of your work when you are done, I would love to see it :)
