License: Attribution Non-commercial Share Alike (by-nc-sa) Intro: Plastic bottle Crab Make a 3d crab out of an old bottle

step 1: materials 1 plastic bottle (one crab per bottle) 1 pair of scissors or whatever cutting instrument you are comfy with optional enamel paint or other pigment that will stick on the plastic

http://www.instructables.com/id/plastic_bottle_Crab/


step 2: cutting the eye stalks cut off the top of the bottle. cut a inch and half strip and fold it up..the eye stalks will be cut out of this

http://www.instructables.com/id/plastic_bottle_Crab/


Image Notes 1. lose the top

http://www.instructables.com/id/plastic_bottle_Crab/


Image Notes 1. cut out a flap from here 2. eye stalks will be cut out of this flap

step 3: cutting out the claws and legs cut two stips on either side of the first flap.. give them spoon shaped ends(refer to the image) we'll fashion a pair of claws from these cut as many more flaps as you like for the legs...i prefer six legs, but some like 8...whatever is biologically accurate i guess

Image Notes 1. eye stalks to come out of this flap 2. spoon ends to turn into claws 3. leg 4. legs 5. legs 6. crab body

step 4: eyes, claws and legs cutout the eye stalks...you could stick marbles or buttons on the stalks for eyes i guess fold the claw-arms so they become more rigid...split the spoon and mke folds like in the image ..this gives you the claws.. the legs are pretty simple..fold fold fold :) and thats about it.. you can decorate yours with paint and whatever else you like :) enjoy dangle this crab under a light or in a window...

http://www.instructables.com/id/plastic_bottle_Crab/


Image Notes 1. eye ball area..you can punch holes in here, or stick something round for the eyes...or just paint em on 2. eyestalks, dont make em too narrow, or they'l tear off

http://www.instructables.com/id/plastic_bottle_Crab/


Image Notes 1. fold down at an angle 2. split the spoon

http://www.instructables.com/id/plastic_bottle_Crab/


Image Notes 1. fold back up at another angle, and voila! a claw is born

http://www.instructables.com/id/plastic_bottle_Crab/

Image Notes 1. add some diagonal folds, to make it more rigid


Image Notes 1. the front legs will be shorter, coz of the spoon shape of the claws...so don't put too many folds here 2. the back legs can be more anatomically accurate..fold up and up again then down then down again

Image Notes 1. if your lucky you'll get this smile when the light shines through the right way... dangle this crab under a light or in a window...

step 5: paint it up white i used acrylic paints, but you could use enamel paint or spray cans too. 1) paint a base coat of white as the primer.. priming the surface ensures that your colours will turn out bright. a common mistake is that people spray on the colours they want.. and then it doesnt quite turn out as bright as they thought it would.

step 6: paint your colours once the base paint is dry, go ahead and paint on your colours. i've hand painted it, so it looks a bit shabby .. for a finer finish i would have used spray cans or an airbrush

oh, ok thanx

nagutron says:

Jan 23, 2009. 3:12 PM REPLY It would be awesome to see an uncut bottle with all the cut marks drawn on it with a permanent marker. This instructable would be much easier to figure out if you did. That being said, the end product looks great!

Cheers Ill get started

Lftndbt says:

Jan 23, 2009. 2:23 PM REPLY That is REALLY good! Keep going with him and add more angles/folds to create even more of a 3D effect. Those claws would look even more impressive, with two more folds down the middle of them so you could give them a real curvature.

Lftndbt says:

Jan 24, 2009. 1:04 AM REPLY Don't get me wrong , he is AWESOME!! Prior to you posting this I had an Octopus, all ready to go. I should post that I'ble and we could have a little under water party.

chaitanyak says:

Jan 24, 2009. 3:57 AM REPLY i almost turned i into a jelly fish, with thinner strips.. octopus sounds good...put it up quickly :) and if you can get your hands on a bunch of bottlecaps or toothpaste tube caps, you could use them as suckers for the tentacles :)
