I had a few high voltage transformers that I wasn’t using and since they make a big spark but aren’t necessarily dangerous I thought that they would be perfect for a taser. The main things I used for this were plastic for the main structure, the transformers, and a 9v battery.
I first had to design the entire thing on tinkercad to then print it. When I first prototyped it I used a 1.5v battery but it was powerful enough so I ended up using a 9v one. Also, the way I designed it was in 3 different parts, the tip, the transformer part, and the battery holder.
To turn it on all you had to do was press on a button which closed a circuit between the battery and the transformer.
