♻ PLASTIC BOTTLE LENS CASE (waterproof) ♻

I made this for my Nikon lens.
You should choose different size of bottle for the size of your lens.
Is waterproofable with innertube.

Step 1: YOU NEED

MATERIALS:
_2 bottles of the same water (better if with flat bottom);
_spongy material;
_zipper;
_dental floss.
TOOLS:
_scissors;
_safety pin;
_needle.

Step 2: CUT PLASTIC BOTTLES

cut the plastic bottles: one a tiny bit longer that your lens, the other 1 cm on top of were it start to become straight. (see photo)

Step 3: MAKE HOLES WITH SAFETY PIN

make holes with the safety pin  all around the edge of the 2 pieces of bottles. 1/2 cm far apart.

Step 4: PUT ZIPPER

sew on zipper with dental floss (i used it 'couse is really strong), using the holes you made before with safety pin.

Step 5: CUT SPONGE

cut the spongy material: 2 circles of the circumference of your bottle and one rectangular piece that will fit the side part of your bottle.

Step 6: PLACE SPONGE

place the 2 circles on the bottom of the 2 bottles, and the rectangular piece all around the side. you can glue them to place (mine just hold themselves in place).

Step 7: DONE! WATERPROOF IT!

you are done! you can waterproof it if you want: cut an innertube in half and sew it like a ring of the size of your bottle circumference (it should be really tight fit) , place it all around  the zipper (this will work only the side of your bottle are really flat, and if you make it tight...anyways I don't want to feel responsible for the safety of your lens!).
