18650 battery sleeve for 3x AAA flashlights like UltraFire C8
thingiverse
I designed a custom sleeve for my trusty UltraFire Q5 flashlight, model U4-MCU, which shares the same shape as the C8. Recently, I made the switch from three AAA batteries to an 18650 battery, and created this new sleeve since I lost the original one. Make sure your flashlight is compatible with 18650 batteries before making the upgrade. The inner diameter of the custom sleeve measures 19mm, while the outer diameter is a precise 22mm.
