Pro tip as a 3D printer owner/user though:
Oftentimes for small elements like this you can just contact the company and they'll send you a knob or whatever. (Probably won't be that lucky on repair parts though)
But I also enjoy the pride of seeing things I've repaired and longevitized with my own equipment. :)
I just grab the serial number from a recently sold one and file a warranty claim on it.
Wouldn't that be susceptible to melting due to oven temps? Or is that probably made from a higher temp filament?
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):
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.
Oh sweet, knowing how to use a knife is right up my wheelhouse too!
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.
Depends on the type of filament used and temperatures that are actually present at the knob. I would say no since the temperature required to melt (or warp) the knob would have to be high enough to cause some pretty severe burns if you touched it with your hand. if the knobs on the oven/range are getting that hot, there is a lot more to worry about here than the knob melting.
I'd say more like 30 cents, but this one's clearly stolen - a real 3d printer owner would have had the right color filament on hand.
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!
Thats going to be a squidgy mess after a long cooking session. Hope he doesn't get plastic burns.
Now THAT is a life hack.
lol when i was an asshole kid i did that with guitar volume knobs
But now it's the only one that doesn't look nicely polished, unlike the other knobs. 😁
If it was MY knob, it'd be polished on a daily basis.
Well done IF_TV!
