My uncle and I build this one together. Is from a dollar store flashlight. Equipped with a protank. The size of the switch only allowed room for a 18350. No fuse or safety measures... If it blows up, it blows up. My uncle wanted to help and he is a master at projects like this. He builds tesla coils and 3d printers so I trust his wire-work. I left the bottom toggle switch to serve as a main power button. Used a switch and 510 connector from madvapes. It took longer to cut the top part of the flashlight head in half than it did building it, and that's strictly for aesthetics. Used parts of the flashlight and super glue to attach the 510 port. Shored the battery with thin PVC pipe so it didn't bounce around. Used a bolt for the positive terminal.
I love this thing. I have a 510 to 510 adapter for tanks that don't fit it, like the trophy or tumbler. Total cost, under $7
