I had been planning to make a laptop stand for a while when I remembered those K'NEX sets that I hadn't used for years. The other Instructables on K'NEX laptop stands either used a lot of pieces, looked too flimsy for my (rather heavy) laptop, or both, so I came up with this design.
The stand should be suitable for a variety of laptop sizes, as it is modular. You can make as many or as few sections as you like and use different length rods depending on the size of your laptop. You can also change the angle of the laptop, too.
Step 1: Making a Single Section
The stand is made of identical sections clipped together. For my 15" long laptop I used four.
To assemble a single section, follow the photo below. For a shallower angle, replace the white rods with green ones and the blue with a white.
Step 2: Connect Your Sections
To connect the sections together, simply connect rods between them as shown in the photos. If you're using anything longer than a yellow rod between the purple clips you should probably use another section. For my 15" long laptop, I used blue rods for the central connection and yellow rods for the outer two.
Step 3: Finishing Touches
Now add any finishing touches you can think of. I added some pieces between sections mainly to add a bit of interest. I might try something like gmjhowe's Cable Catcher later.
Now you're finished! I hope you find my Instructable useful.
