This is an updated model of the 3d printed pepper spray gun, redesigned to use less plastic, look better, and have a spring return on the trigger. It is designed for use with 'Mace' brand spray cartridges. (All of the hazardous components are contained within the cartridges. The printed plastic gun is not inherently dangerous.)

Pepper spray is legal for use as a self defense tool in all 50 US states, although possession may be regulated in some cities. Never spray unless you feel threatened. Improper use could result in criminal action.
