This Parabolic String lamp is made out of laser cut wood, yarn, and a pendant light kit.

I was thumbing through some vintage interior design magazines and found all these kind of cool examples of Parabolic String Art.

I examined it closely and figured out how the illusions of curves appeared in the string art. I was curious if the same principle could be applied to a curved dimensional object. I tinkered with a few different designs, and materials - the lamp featured in this Instructable was actually the fifth iteration in my design process.

Step 1: Laser Cutting

I designed the lamp, and it's feet in Illustrator. It was a little tricky to figure out a design for the notches along the wheel, I tried teeth vs. holes vs. notches vs. kerf cuts.

It turns out I needed a notched hole for the best way to catch the string. I used a laser cutter to make my cuts into 1/4" plywood, but I think I could achieve the same effect with a band saw and a drill press. (And a lot more time, this cut took 5 minutes on the laser)

I have attached my files to this step -let me know if you need a different file format.

Step 2: Assemble the lamp.

I used this Pendant Lamp Kit from Ikea. It turns out these aren't sold in California any more, but we had one lying around.

I designed the hole large enough to fit the socket, but small enough to grab the plywood with the coupler in the lamp kit.

Step 3: Fins and Bulb

I added all of the fins to the lamp, one at a time, making sure to connect it all the way into the notches.

After they were all installed, I screwed in the light bulb. Pretty easy step.

Nice work. However I don't have access to a laser cutter. I do however have a scroll saw. But your PDF does not print in a 1 to 1 template. That would be very useful. Thanks

this is absolutely gorgeous!! i totally love it!!
