Been innawoods hunting, and of course your hands fucking freeze off. Using hot hands hand warmers works ok, some packets work better than others. Was thinking about making my own little hand warmer with a 9V battery and remembered I have this battery (pic related, coins for size) from an airsoft gun. Was thinking about using one of those heating stickers that you put under a 3d printer base. Think that would work? What kind of components would you recommend?
