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.
