Fulton MX-991/U Flashlight Conversion | 3D Printed 18650 Battery Housing & LED Module Upgrade

Description: In this video, I show how I converted the classic Fulton MX-991/U flashlight to run on a modern 18650 rechargeable Li-ion battery. Using my 3D printer, I designed and printed a custom housing that perfectly fits the 18650 battery and LED module inside the original flashlight body. This upgrade not only modernizes the flashlight with a rechargeable power source but also improves runtime and brightness. I walk you through the entire process — from 3D printing the battery tube to installing the LED module and wiring everything safely. If you’re interested in DIY flashlight mods or 3D printing projects, this one’s for you!
