Thanks yea I made sure to add this Safety section to my write-up on how to build this yourself, and I reference back to it a lot, so it’s painfully clear.

I printed this in PETG, but ideally you use UL 94 V-0. I did make sure everything is very well insulated, and pulled hard on every connection to make sure it’s held down properly.

Safety

This part carries live mains. Mains wiring kills people who get it wrong, and a fault in a printed enclosure can start a fire.

Do not build it unless you are competent to wire mains and permitted to do so where you live. Sleeve or shroud all live terminals. PLA softens around 60 °C, PETG around 80 °C. Neither is flame retardant. Only a UL 94 V-0 filament is.

Wire the protective earth if anything you plug in needs it.

Build it at your own risk. I take no responsibility for injury, death, fire, or damage resulting from anything in this repository.
