3V LED Flashlight Bulb

As I have stated before, I love flashlights. It is an addiction. Another one of my addictions is not being able to throw useful things away. So, as the world has transitioned from incandescent flashlights to LED, I have resisted the urge to throw away all of my old incandescent flashlights. They still work, so why should they go to a landfill? They do not work well, however, when compared to the newer LED lights. So, conundrum.

I could spend more than the light is worth to buy a replacement LED bulb. Or, I could make the bulb myself. Enter 3d printing technology and a little ingenuity.

So began my 3V LED bulb project.

NOTE: By using 3V LEDs, this bulb is designed to be used in flashlights that use TWO 1.5V batteries (Battery sizes AAA, AA, C, and D are all 1.5V).

Tools and materials: (I do not know why this shows up as larger text when published)
1. an old incandescent flashlight
2. a 3D printer and filament
3. a drill with a 1/16" bit (only if needed)
