High Voltage Probe with Voltage Devider

Starting with warnings:
Dealing with high voltage is dangerous. So use this design on your own risk only!
Only use this design if you can assess risks by your professional qualification.

This design is not suitable for high voltage power grid application, because it is too short to provide sufficient safety distance. It is only suitable for high impedance sorces.

Since I fond no information about the isolation properties of PLA, I assume PLA ist not suitable for isolation purpose. In consequence it is not suitable for this project.

Beside the design provides high creepage distance on its surface, fdm prints tend to have fine fissures witch might pry out the isolation. Especially if the part is wetted with conductive dirt.

Resistors have a separate voltage rating. The voltage they can withstand is not only limited by the power dissipation. They are commonly rated between 300 and 500V. That's why I'm using 30 resistors in series to achieve 10000V
