I have always liked LED's and since their existance, I have been using them in a lot of projects, looking for a small box where to put it, using cheap materials to create a nice looking finished project. After a lot of designs with trial and error, now I designed a template to cut a PVC sheet (acetate/mylar) and made a box for the batteries, the switch and the led, without even using glue or solder.
So here is my first Instructable to teach you how to do it, and use it in a lot of ideas (I will give you some of them). I know that it looks like a kind of led throwie but it isn't (we don't have to throw things, it's better to recycle them), because its designed to put it in an exact place to illuminate whatever you want. You can change the batteries and either add to the base a piece of magnet or some velcro or double side tape, so that you can put the box on any place. The box also has a switch tab so that you can turn it on/off, Hope you like my project.
