The flashlight built in this Instructable is fully 3d printed and runs on a 18650 rechargeable battery. It is a little challenging to build if you are interested in enhancing your maker skills. It requires a small amount of supplies, and I decided to share a version without a LED driver since 3 x 1watt LEDs are inexpensive and flashlights might not be used as often as household lights, therefore a reduced lifetime might not be as dramatic.

Step 1: 3D Print the Required Files

Links to the files will bring you to Thingyverse, where you can download the 4 required files to print the flashlight.
