♻ 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.

YOU NEED

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

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)

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.

PUT ZIPPER

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

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.

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).

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!).
