I modified the parts from a user on cults3d who made a really nice printable model of the Xenozapper from Satisfactory. I basically made a round hole all the way from top to bottom to fit a 18650 Li-Ion battery and a high voltage generator as well as a button and a charge controller for the battery. The high voltage module I used was similar to this one from [Ebay](https://www.ebay.de/itm/311688245090) and as charger I'm using a standard TP4056. To modify the files I mainly used Fusion360 to convert the STL's but for most of the more complex parts where a conversion to CAD isn't easy and that only needed a simple hole threw the middle I used some modifiers in PrusaSlicer.
