Based off Peter's Grenade and my warped mind. Fits Bic lighters but might get you in trouble and it's big for pockets. +Brims + Some supports

Had to do some rebuilding and adjustments to adapt the grenade model. Re-enforced the spoon (release lever) and made a new pull ring that is more printable and less likely to break off.
