Step 1: Materials/Tools
-Cardboard (I got mine from my webcam package)
Step 2: Trim
Step 3: Trace and Cut
Then cut out the sides and cut the sides, front, and back about a quarter inch short.
Step 4: Placement
Next fold the duct tape around the cardboard. (Picture 2)
Place the bottom piece of cardboard on a strip of duct tape, and and wrap it around.
Step 5: Test
Wrap it in duct tape and trim off any overlap.
Place it on a strip of duct tape.
Place one end of that strip into the holster and use the lighter to press it into place.
Wrap the rest of the duct tape around the bottom.
