Still cheaper than getting a 3D printer and filament and stuff. And CAD/CAM software.
It’s true that you should not expect to save money in the short or long run with 3d printing as a hobby, but if it’s your thing then it’s nice to have a hobby that’s occasionally useful. Also, autodesk fusion is free for consumer use.
Software is free if you aren’t using it for commercial use. Fusion 360, onshape, etc. are all free for personal use. And that’s assuming someone didn’t make it already and share it free.
Filament costs $17 for 1kg of perfectly fine plastic. You’d probably use 100g at most for this, so $1.70.
A Bambu A1 mini is $200, and is a modern, high quality printer that would be fine for this project.
So you only need like a half dozen of these projects to come out ahead.
To be clear, I’m the last one to say one shouldn’t invest in money saving innovation. But the breaking even should be number one priority. I, for instance have all kinds of energy savers in my house that have cost me several hundreds. They’ll only be returned in a few years and I need to manage them properly.
If you do not have a 3D printer and CAD software, you are 100% right.
If you already have those things like OP, then why not just design / print one? I am also a 3D printer / CAD person, and I love designing replacement parts that are wither too expensive, or often impossible to find. Mostly though, I design and print things that make my and my families lives easier / nicer / more convenient. And they are customized to the exact item and function, something that you would most likely never be able to get in a store or online.

Just to name a few things.
I wish I had pockets big enough to replace the flimsy Bosch drawers in my fridge that start to shatter as soon as you pull just a tiny bit harder than normal.
There are 3d models for some fridge drawers. I have a Frigidaire with similarly flimsy drawers and found a model for them.
China mastered copying things well. A five pack of replacement knobs that actually match is $34 on Amazon. A crappy homemade knob for a $4000+ range is crazy.
And Bosch makes and generally stands by their good products. Yeah they’re a company, but they’re not the worst!
Also, where did original knob go, I need to know.
Some things are better left unknown.
China has also mastered modern slave labor. That someone makes thier own replacement instead of ordering some small uncomplicated part from across the globe isn’t crazy, it’s self-reliant and smart.
But that’s, like, just my opinion man.
Oh I would go for the OEM part ten times out of ten, especially for such a nice appliance. Instead this person opted to make some plastic waste that will eventually be in the Ocean after we are all long dead.
Completely agree that Amazon garbage is terrible for humanity
I definitely agree that less plastic = better in general. But if you’re going to 3d print stuff, at least this is functional.
And I’m not here to argue. God it is nice to have a civil discussions on social media.
Sorry if I came off as argumentative. That certainly wasn’t my intent.
I was just trying to make the point that this person spent a lot of time and effort to do something subpar with plastic.
You didn’t seem argumentative to me at all. I’m genuinely happy to disagree about something and:
-just have it be civil
-no one takes it personally
-we find things we can agree on

It goes farther than that! The 34$ 5 pack is only that price because its already here in america to be shipped in a day or two. It came from china, where you can order the same thing for 1-5% of the price if you are willing to wait a month to receive it.
I was gonna bitch about it too but the cheaper Bosch ranges use the same knobs. It’s an off the shelf part that Bosch is charging a ridiculous premium for.
Channel locks, adjustable wrench, or plyers are also acceptable. Plus then ya know damned well where they are.
So one is creative and solution seeking and now proud about himself and an inspiration to others and the other one – not, but just a thief.
Just a thief?? That’s creative, solution seeking, and ecologically conscious problem solving right there
He’s an active initiator of the broken windows theory and thus not only a thief but acting anti-social by destroying virtues and morale and thus social safety, coherency and teamspirit. He’s a selfish sociopath.
He’s a selfish sociopath
Sure, being a thief is bad, but one case of theft doesn’t instantly make him a CEO.
Broken Window Theory is a load of bollocks: https://cssh.northeastern.edu/sccj/2019/05/21/researchers-debunk-broken-windows-theory-after-35-years/
If the knob on your stove breaks while it’s still new enough to be sold on the floor of a Home Depot? Yeah, the theft wasn’t by the guy who took the knob.
If the knob of your new-bought stovebreaks to talk to the seller or the manufacturer and request a new knob if it was a manufacturing problem. You don’t go around and steal knobs from innocents.
Home Depot is not innocent.
-Anti-union
-Massive donation and lobbying efforts to Republicans and Democrats (but they definitely go harder with Republicans, if you look at the numbers, and they’ve donated specifically to white supremacist candidates)
-Underpaid employees
-Violated the National Labor Relations Act NLRA
Fuck 'em
Don’t forget they donate to gay and trans reeducation camps right here in the US.
Yeah Lowe’s sucks but I’ll go there first every time.
Lol.
This reminds me of a story my mom told me over the holidays about buying a fancy sweater at Sears one fall. By mid winter the zipper had broken and she went back to Sears but they didn’t have a replacement, and she didn’t want a refund. They eventually agreed to have her take it to the tailor in the mall for them to replace it, and they would cover the receipt. She did and they did.
Blew my mind. If I honestly thought I could contact Maytag or Bosch and actually get someone on the phone to send me a replacement knob, I might bother. But I’ve moved past “try to contact the company with a reasonable concern” a long time ago. Which is what they hope for and why they make it time consuming and pointless. I’ll take the path of least resistance.
If home Depot goes out of business because of all the stolen knobs, I’ll cry myself into Rona every day (I mean that, I hate Rona and I use HD daily)
Shoplifting is a noble crime.
Little sanding and silver Rub 'n Buff on that print will make it look a lot better and closer match to the rest.
Or even simply moving it to the middle of the set of three for less distraction.

I was reading some “I am a master shoplifter” threads on Reddit, and honestly I don’t know why people don’t steal more stuff.
I thought they banned the shoplifting subs. No?
They did, it was an AMA.
But what the hell happened to the other knob? I’ve done a lot of stupid shit around the stove but I can’t imagine what could happen to it.
Kids are a force
Wait you have kids and still sink money into crypto shillcoins? 😬
We wanted to fight corporate bailouts too, and it worked out well enough that we could afford to have kids.
I just grab the serial number from a recently sold one and file a warranty claim on it.
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!
Now THAT is a life hack.
Wouldn’t that be susceptible to melting due to oven temps? Or is that probably made from a higher temp filament?
What’s the melting point of the regular filament? You’re supposed to touch the oven knobs it so it’s probably not much higher than 50 degrees.
50° K?
Hopefully if it’s a decent oven there isn’t that much heat on the outside. I guess if you just left the door open, it might eventually melt
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.
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.
But now it’s the only one that doesn’t look nicely polished, unlike the other knobs. 😁
Isn’t that just selling?
Thats going to be a squidgy mess after a long cooking session. Hope he doesn’t get plastic burns.
I think something might be wrong with your oven uh… my knobs don’t get anywhere near the glass point of PLA when I’m cooking something.
