    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. :)

      One doesn’t buy a 3D printer to make a knob. One is suddenly presented with a need for a knob (or a thingy, or a flangle, or a twizzlet…) and suddenly remembers, “hey - I have a 3D printer.” Followed by “I wonder if there are any matching designs in one of the several massive free databases of models.”

      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.

        I wouldn’t say I’ve made back my investment on 3D printing in the past half a decade I’ve done it. But in terms of “prints for friends” like this one above I may be close. Plus there’s just something nice about going “I need a measuring cup for dog food” and printing one to the exact serving size.

            I just use PLA. PLA itself is good safe, but occasionally the additives aren’t, so I don’t use any for human related stuff. It’s also worth considering that the layered approach can allow for bacterial growth, so unless you treat it (e.g. epoxy seal it), you’ll need to wash it fairly frequently to curb buildup.

                To be fair, that’s the case with pretty much all plastics.
                Tupperware shouldn’t be used to reheat food in the microwave for the same reason, yet that’s it’s most common use generally.
                Untreated PLA is more brittle than commercial food-safe plastics though, that is true.

      The type of person to do this most likely already has a 3d printer, and cad software is free for personal use. The electricity and filament cost for this part would be a few cents and it would take minutes to print on modern printers

      Even if you didn’t have a 3d printer it would be significantly cheaper to use a 3d printing service to order the part, than to buy OEM replacement knob

      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.

            No, it doesn’t.

            The recent 1.0 release is actually very good. It is probably better at this point than some of the entry level commercial options and most importantly compared to those is not intentionally hobbled in any way.

            The time for everyone to stop parroting how “everyone knows” that FreeCAD is unusable is… now. You can go ahead and delete that one; it’s time to learn a new soundbyte.

                Yes. The 1.0 release was in November. That Ondsel fork in your video was based on, I believe, the 0.22 version.

                The 1.0 release actually prompted Ondsel to shut down entirely, as they are now largely redundant and attempting to monetize a FOSS program was probably doomed from the start anyway…

              Come on. The 1.0 release is a huge milestone, but saying it’s better than the entry level commercial options is just disingenuous.

              I have actually switched over to it because I run a small 3D printing business as a side income, which isn’t nearly profitable enough to afford an onshape license, and although Fusion360 has an affordable startup license it simply won’t work on Linux and my hackintosh laptop isn’t powerful enough for cad.

              It is at a point where it is very usable if you are willing to invest the time needed to learn it, but the learning curve is much, much steeper than that of OnShape or Fusion360, especially if it is your first CAD program. There is also a huge lack of beginner tutorials for it, and the documentation is intended for advanced users, which complicates the learning curve even further, because Fusion360 and OnShape have a huge amount of beginner tutorials for them.

              For a hobbyist that just wants to model a few things and not sell them I would always recommend OnShape or Fusion360 over FreeCAD, or even Tinkercad if said person just wants to model extremely simple things.

              Nah it’s not you, FreeCAD is perfectly usable for something like the above referenced knob but even mid-size assemblies really have problems. I personally find the workflow to be bad and irritating beyond my ability to express in words and I can’t imagine how frustrating it would be as a new user to work it out for yourself while at the same time getting used to thinking of objects as collections of operations. It’s a great lightweight program for people who already know what they’re doing and that value FOSS, though. 1.0 really fixed a ton of the issues, but it still has the “Blender UX” problem that seems to plague all big FOSS projects…

      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.

      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.

      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.

      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.

        A while back I would use those local secondhand auctions that mostly dealt in amazon returns. (As opposed to directly buying from amazon.)

        I’m surprised how everything would be intact for a lot of items, but most commonly if I got bamboozled, it was something like, everything is fine except for missing a set of screws, or a single crucial knob or something.

        People literally will just order the same thing again, pull the part they missed, and instantly return it. Which is especially scummy when it’s no longer a secret these returns just get destroyed or incinerated for no reason.

        It’s just disgusting consumer-brain behavior. (Amazon, of course, being sheer evil, enjoys the market advantage of a “no questions” return policy.)

        If it was a very specialty piece beyond a simple hardware store run, a lot of times I’ve been lucky enough to politely contact the manufacturer of a thing, sometimes I tell them I got it as a gift so they don’t ask for a proof of purchase. And they’ll just send me the missing bit. Free. Super simple. The most I had to do was take a picture of the model tag.

        The fact that this was too much for people to bother with grosses me out.

          Not to say this behavior is okay, but there are some companies that also just exploit the alternative to high heaven, like the post shows. You can pay $20 for a 12 cent replacement part, or order one and return it. Some people will pay for the part, but significantly less will when it costs and arm and a leg for something so cheap.

        Depends on the material. ABS would be a decent material for this application - as long as you have a decent enough setup to scrub / clean the air in the chamber / room.

        PLA would have a hard time in that position, PETG might be OK, Nylon may creep after too many heat cycles. Depending on how hot those parts get this is.

          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)
