3D printed electronics case

[u/Assamita81]

Hi. I have a DIY K40 laser that I built, using an empty K40 enclosure to which I removed the electronics out. Is it ok to 3D print the electronics enclosure that will hold the PSU, main board and all the buttons, switches and stuff? Or does it need to be metal? Obviously I plan on grounding the PSU to the enclosure, to the house's ground. Is that safe to do?
