Hello Folks, I’m thinking about printing a plug shell for my golf cart charger. I bought one off eBay and it’s a tad to wide. My question is abs or pla safe to use for holding electrical wires? Here’s a pic of what I have and the other pic is what would be inside. I basically need to print the two black pieces just a tad not so wide. Is this possible or am I going to burn my house down lol? Thank you!!

Hi @MadamX it really depends on how hot the plug gets. PLA has quite a low glass transition temperature (the point where it starts to go soft and deform) at only around 60C so I’d probably avoid that. ABS is much higher at around 105C, but even that may not be enough if the plug gets very hot.

If the plug gets very hot you may have to look at printing with a High Temperature Resin via SLA rather than FDM.
