my oven only goes down to 170F, it'll wreck PLA, I have dried nylon with it once, it seems like other people have done it so I thought it was safe, but I will no longer continue to.
Turn it to your lowest setting and leave your door on it cracked. 170f is probably fine for a while, but your oven most likely swings from 150 to 200+ or so, it's not holding a steady 170. They typically aren't very accurate, especially at lower temperatures.
Still probably not a fantastic idea to do in an oven you also cook in, but you can do it without destroying your filament.
