Reusing vape batteries in flash lights? Is this a crazy idea. (self.flashlight)

So people throw out disposable vapes all the time. I cracked one open to take a look and it turns out they have a 18500 battery in it. So I was thinking of 3D printing a spacer to make it the same size as a 18650 and putting some shrink wrap on them. I just wanted to see what people who know more than me think. Is this a bad idea that is going to burn my house down? a waste of time perhaps?

I did a trial run in my wurkkos fc11 and they seem to work, it charges and looks just as bright.

Should work fine. 18500 batteries have the same specifications as 18650s except for, of course, a smaller physical size and so a smaller capacity to go with it. Other than that, you should be able to treat them more or less identically to a normal 18650.
