I'm trying to design a circuit for creating 3D printed accessories to work with my high voltage generator, which outputs up to 45 kV at less than 1 mA. I want to avoid 3D printing prototypes, especially since conductive filament can be pricey. I'm currently using Tinkercad for modeling but I'm open to other software. My goal is to understand the expected spark distances (between 5 to 20 mm) and the voltage when the device makes contact. I have a basic understanding of circuit diagrams but I'm a bit rusty on the practical applications. Any advice or good resources would be greatly appreciated!

You're moving into physics territory here, not just circuit design. Keep in mind, factors like humidity and air temperature can affect how those sparks behave. If you're considering printing accessories, think about using standard filament and applying electroplating instead of relying solely on conductive filament. It'll save you some bucks and give you better results.
It's great that you're exploring this, but be cautious! Most electrotherapy devices use AC power since DC can lead to electrolysis, which is definitely not what you want. Look into TENS or EMS devices designed for safety; they might be what you're after. Just remember, working close to the body with high voltage can be risky, especially in the sensitive areas you mentioned.
