I found a box for an iPhone 4, sadly missing it's contents. It is made out of pretty stiff cardboard. I thought it would make a nice little drawer. This is how the IDrawer was born.

Step 1: Materials Needed

iPhone 4 box, don't know what the other version boxes look like.
Tape. I used duct.
Piece of cardboard at least measuring 5" x 2 3/4"
Knob
Self tapping screw a little bit longer than the knob
Ruler and cutting device

Step 2: Remove the Insides of the Box

Step 3: Find Your Cardboard

Cardboard from a misc box. These were yummy!

Step 4: Measure and Mark

Measure to fit inside edges of box top. There is a space there. Lid is taller than the bottom by about the thickness of my cardboard.

Step 5: Cut the Cardboard With Instrument of Choice

Step 6: Remove One of the Ends of the Top

Step 7: Place Cardboard in Bottom of Box Top, Leave Inside in Place to Hold the Cardboard

Step 8: Start Taping and Trimming

Step 9: Add Knob

This is a little porcelain knob that I found and had saved to find a use for it someday and I did. Used a self tapping screw a little longer than the knob. You can measure to find the center, but I just eyeballed it. Put a piece of tape over the end that protruded inside. You could use a small bolt instead.
