Zippo catalytic hand warmer plug

thingiverse

Zippo officially tells you that once the burner starts, there is no way to stop the catalytic reaction. But you can actually just pull out the catalytic burner while it is burning and stop it. (please use a cloth please, it's hot...duhhh) You can't really store the hand warmer with lighter fluid still it in, because the fluid eventually evaporates. I made this plug that will plug up the opening and stops the evaporation. As a bonus, it holds the burner at the top so it doesn't rattle around.
