This is why I always buy cheap vice grips whenever I see them in a box of tools at an estate sale or something.

"Oops, I broke a handle on (thing)."

Clamps vice grips on the bit left over

"Fixed it."

Right now both of the seats in my truck just have a vice grips for the reclining lever.

Kids are a force

From experience, we tend to use the same two burners, and one particular one, the most, by far. (Front left for us) After 15 years, the plastic on the underside of the original knob got worn and loose and almost broke. We rotated the burner knobs. The oven knob is doing the same thing, but it'll need to be replaced or repaired. Like someone else said, they aren't usually all metal construction, there's plastic on the inside.

Not really. You can print it out of ABS easily enough if that's a concern, given that there is a good chance that is what the knob on any given residential range or oven is likely to have been made out of by the factory anyway.

As a matter of fact, since this is directly in my wheelhouse (not that wheelhouse, the other one) vis-a-vis both 3D printing and whitegoods, let's take a look.

Being in the unique position to be able to do so, I grabbed a knob off of a random smattering of ranges. Here's what I found from the ones that didn't require taking them apart further to find the markings or scraping at them with a knife or something (hey, there's the other wheelhouse):

• Maytag (Whirlpool): Stamped "ABS" on the inside.
• Bosch "Industrial Style" (similar to OP's): PBT
• Whirlpool: PET
• Verona: ABS
• GE Base Line: ABS

PBT has a pretty similar melting point to ABS at ~235° C. With ABS it's complicated, but I print ABS at 260° C for what it's worth. PET is also typically given around 260-270. So these are all pretty similar to each other.

TL;DR: You should be fine with ABS.

Glass transition temp of PLA is around 55-60C - that’s when it starts to get malleable. I’d be pretty surprised if the oven knobs get that hot.

Or even simply moving it to the middle of the set of three for less distraction.

Much more realistic that we'd intentionally spend $40 on a specialty roll of filament to have the right color and finish for that one specific print. See, I'm totally saving money! Right after I print, like, nine more of these!
