Had to read like 50 comments and nobody pointed out you can just buy a generic knob for like $1. Hell your used building center would be 50 cents. WTF world do we live in where the solution is CAD and 3D printing for something so trivial. It’s like using a nuclear bomb to kill an ant nest.
Oh yes! The correct answer is to 3D print a plastic knob for the front of an oven. There’s not going to be any heat issues there! And no one can deny how beautiful that black knob looks next to the brushed metal.
The knobs on your oven are overwhelmingly likely to be either completely made of plastic or contain a large percentage of plastic already. Typically they’re made of ABS or PBT.
PLA probably isn’t a good choice for this application but you could absolutely print some knobs in ABS or ASA and you’d be fine. You can even get PBT filament, but that’s probably more hassle than it’s worth and ABS is cheaper.
There is no single correct answer. There often isn’t, in fact.
As for heat: You can treat PLA to be more resistive to temperature and even at stock, untreated, cheapest PLA wont just deform from hot air escaping since the thing melts at 190 and the air wont be that hot for long enough. It may deform with regular use though. You also don’t have to use PLA and use something more temp resistive.
Beauty? Eye of the beholder. Its a conversation piece. Its something you point at and say “I made that”. Its wabi-sabi, I like it.
The stock knobs are most likely plastic already, but I do agree the black knob looks stupid. It would probably look a lot better to print matching replacements for all of them.

Look dude, fuck those ants.
Once you have the printer and the knowhow, it takes like 5 minutes to draw and 20 minutes to print at a cost of like 0.10 €
It takes longer to go to a location and buy it at a much higher cost. So why should you?
Its also something you built with your hands and brain. There are few things which feel as good.

190 celsius, I’d like to add.
If it melts, just print another!
