How to make an inexpensive, collapsible light box.

by on Mar 23, 2009

This weekend I finally decided to try my hand at making a light box. I liked a tutorial I found over at DPS where the maker used a box as his structure. It’s a great, inexpensive way to make your own light box. Its downside, however, is that it’s not collapsible. There was only one thing I could do: Grab a piece of paper and pencil and see if I could come up with a way to adapt the tutorial.

To make one you’ll need:

  • cardboard
  • a utility knife
  • tissue paper,
  • tape or glue-stick
  • mailing/packaging/or duct tape
  • a straight-edge
  • matte poster board

First, I cut five pieces of cardboard into 18″ squares and then cut 14″ squares inside 3 of the squares. Then I laid them out as shown below.

Next I taped tissue paper over the holes of the 3 squares.

Then I taped the five squares together, making hinges using packing tape. I started with the lower left square, which I folded up, laying it on the square right above. I taped my hinges, and then unfolded the lower left square.

I moved on to the center square, which I folded over on top of the left square. Again, I made two tape hinges.

Next was the far right square. I folded it over on top of the middle square and made my hinges.

Finally, I folded down the top right square and made my hinges.

When I was done, I reinforced each hinge by tapping over them on the sticky side/side facing me.

I then added small strips of cardboard as shown below to act as stops for my poster board. As it turned out, I only needed the one on the bottom left square.

This is how the whole thing folds together into a cube:

And this how it looks when folded together for storage:

Here’s a pic with the poster board in place:

See how the stop stops the poster board from sliding down?
