Stun gun (from a lighter)

A simple stun gun that can be built from a lighter

I tested it with different lighters and it worked with all of them

Whether it works has nothing to do with whether the lighter is full or empty

Only 12 grams of filament (and an (empty) lighter)

To build the stun gun, you only need the piezoelectric igniter (flint) from the lighter, and in my cases, it was quite easy to remove. This piezoelectric igniter generates the voltage that ultimately creates the flame, and we need this voltage to produce the electric shock.                   

This is how it normally looks at the beginning

                                               Afterwards, you can, for example, insert a spatula into the small gap

                                                        Then you can pry the cap to the side to open the lighter

 After that, it should look like this

                                               Now the cap, where you normally press, should be easy to remove

                                       If everything worked, you can now remove the piezoelectric igniter from the lighter

      In my experience, the round cylinder comes in two different sizes. One with a diameter of 5.4 mm and         one with a diameter of 5.6 mm (or between these values). These were the sizes I had in my tests; I cannot                   guarantee that there are only these two sizes, but for this case, I have uploaded an additional STEP file so that you can               edit everything as you wish.

If you have now removed the piezoelectric igniter, you only need to install it into the stun gun.

                                                               When the parts come out of the printer, they should look like this

                                               First, please insert the piezoelectric igniter into the designated holder

                                                            After that, please place the bar as shown in the picture

                                                                           Now place the bar onto the piezoelectric igniter

                                               Now firmly connect the two parts by pushing the axle through them

                In my case, it was already firm enough, but if you wish, you can put a small drop of adhesive (e.g., superglue)                   on the axle and press the rectangle onto it. Then it should be secure. 

                Caution: Do not use too much glue under any circumstances, as everything will stick together, and you won't be able to use it anymore.

                                                                     If it looks like this now, you've done everything correctly :-)

I want to point out again that you should only use it for fun; it is completely harmless, but I just wanted to say it once.

I want to emphasize again that this stun gun is completely harmless, as only a small electric shock is generated

It is suitable for scaring someone but not for causing serious harm to anyone.

I hope you like this model. I kept it very simple and didn't add any unnecessary things. This way, it uses little filament but still works.

If you want to modify it, feel free to do so, as I have uploaded the STEP file for it

You are also welcome to sell the model if you wish
