This is a simple solution to put a 18500 into something that require 18650. After you print it out, you will need a #8-32 x 1/2" bolt and #8-32 nut to make it work. I've trier galvanize, stainless, and brass. I can't tell the different on how they perform in my U11 flashlight. My Sanwa Digital multimeter can't tell the difference in resistance among them.
