Introduction: Cheap and Easy to Make Toolbox

what you need

-5l rectangular shaped water bottle
-peace of rope

Step 1:

Make opening at the top of the bottle and two small holes at top side

Step 2:

Wrap the rope around the neck of the bottle several times, tie two or more nodes to fix it in place.
Then pass the rope through the holes and tie a knot

Step 3:

This box cant be used for heavy tools and  filled to the top because bottle plastic if very thin and soft; you can improve a bit this design  if you use piercer to make clean holes for the rope and use thick  shoelace instead of  the rope. In the middle of the bottom of the bottle plastic is thickest and hardest so that s the right place to make hole for the shoelace.
