Taser - The Mini Tickler (Mô hình súng điện mini)

I will give a brief rundown of how this should be assembled:

• There are two parts, the main body and the taser cap. They are to be super glued together once all the electronics are done.
• The power source is a protected 18350 li-ion cell
• The charging method is a USB-C female chip 
• The high voltage source is one of those cylindrical high voltage generator 
• The safety switch is a mini rocker switch 
• The active switch is an illuminated 12mm compact momenetary button from aliexpress
• The wiring is 24 AWG.
• The taser cap should have M2 screws driven down each plastic prong. Since you can't solder to steel, there should be a brass M2 insert nut screwed onto the end of each M2 screw, which you can solder the high voltage leads to.
• Before putting together, seal the junction between the high voltage leads and the screws with hot glue.
