I’ve had one of these 3d printed keys in my wallet as a backup in case I get locked out for 5 years now. I certainly don’t use it often but yeah it holds up fine.
The couple of times I have used it works fine but you certainly want to be a little extra careful with it. I’ve got locks that are only 5ish years old so they all turn rather easily, and I avoid my door with the deadbolt when I use it because that would probably be too much for it.
Mine is PETG but for how thin it is, it flexes a lot. I figured flexing is better than snapping off, but I think PLA or maybe a polycarbonate would function better. A nylon would probably be too flexible like the PETG.
