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.
