I am an old Electrical Engineer (74) and have been using 3D printing for 8 years. I have viewed your video for over a year and they are really good application points. The thing I use the most is not to look at form but look at fit and function. That is what I determined from watching your videos. It makes the repair items better and that is what I enjoy doing and not to sell. Most recently my wife was have trouble turning the cranks on our casement window because of the blind in the way. I created and extended knob past the blinds and she can now open the windows easier. Thanks for your pointers.
Love the "Universal Oven Knob", great application of Compliant Mechanisms. (I recently fixed an oven knob, printed just a "collar" to constrain the outside of broken T hole - a 5min print that works way better than previous tenants epoxy attempts)
Knobs is one of some things that seems to be very basic. But you can't imagine how many times I couldn't find the one knob our clients wanted. You look at seemingly similar knobs and they're all wrong size, wrong knob shape, wrong shaft diameter, wrong shaft shape. You'd think clients were picky but they weren't it's just there's always a knob that just is out of stock and you can't replace it.
I like the optimism but additive is an expensive way to make a simple part like a pull. Also most people don’t want plastic and to get an acceptable finish will require post processing that would negate a lot of the benefits.
I typically don't comment, working on it...Since audience feedback is very beneficial to the creator... I LOVE your videos bro!!! The production, organization, visuals and structure of how you and the team produces these videos of 3D printing technology, provide engineering knowledge, insights and ideas are phenomenal, so inspirational as well!!! Love what you and the team are doing!!! I def share with others of interest of 3D printing and design this channel. Keep up the amazing work of amazing content!!! You guys rock!!! 🙌
I would like to see that universal knob in use on an oven. I am concerned it will just slip. I know you can thicken the spring but would like to see it in use in a video like this. With your print services, can i put a bunch on a build plate and sell them in sets so the customer is not paying for shipping individual knobs?
Where is that oven knob available? I really need this files for my oven or for friends that ask for a replacement and then I have to tell them I have to come around take measurements but this thing is amazing
FDM 3D printing has so much value in the variety of things you can make without needing to make it out of many different parts. I think the issue is the look, I've been 3D printing for a long time, and I still look at any of the parts you are saying and Im like "definitely very functional, but looks like garbage". SLS is much better in this regard, but its much more expensive and messy and harder to get into.
For one-off knobs, I totally agree with you. In general, however, I doubt you could make a 6 pack of cupboard knobs with screws AND brushed nickel finish for A$11.25. That said, 3d printing is a GREAT option for spare plastic parts for discontinued products. In that way, it saves products from going into landfills, and that's a good thing.
Not just discontinued products, but customized, weird crazy shapes, generative design, out of the world that mind can think of products that can't be molded without investing thousands even with limitation in molding. In this case, a cheap but specialized 3d printed knob. Lol
funnily enough, I had someone commission a knob for a ceiling fan recently, but I just modeled the exact same knob instead of a compliant mechanism like yours. Thanks for sharing!
The most expensive plastic knobs are found in high-end applications like luxury audio systems, medical devices, automotive interiors, aerospace controls, and custom designs. These knobs often use advanced materials (e.g., PEEK, PTFE) or premium features like coatings, sensors, or integrated lighting. Prices can range from $50 to over $300 per knob, depending on their complexity, precision, and market niche.
Correction re Injection molding: Snap-fit a ring containing the complaint mechanism into your knob design. As a 3D printed design I think this approach might be good as well if you send the knob part out to print in metal. Then you have some really nicer feeling metal knobs - than anything injection molded. (Might get hot from radiant heat though that's a different problem though)
In addition to the knob, you now have to design the ring and the manufacturing process for that ring then get those rings made, PLUS a way to snap the ring into the knob for each item. None of which is cheap, easy or fast.
The tricky bit is getting people to accept the aesthetics of 3d printing. I remember when anything made from any plastic was considered cheap, ugly, unreliable and undesirable. Fast forward a few decades and now we prefer plastics to wood and metal for a lot of things. The same thing will likely happen to 3d print items.
We prefer plastic on a cost basis but almost always still prefer wood and metal for aesthetics. That’s why wood/metal editions of products are marketed as deluxe/premium. I don’t expect the perception of 3d printed parts as being cheaper/uglier to change but I do expect that price trade off to become seen as acceptable as time goes on.
I like the compliant mechanism built into the knob. The biggest issue I see with 3d printing is : Ok you make anything .....go....uhhhhh ok....now what? It is so open it causes a paralysis. It will take people growing up with this technology to really show us how to use it in everyday life to its greatest advantage. Similar to how young people really use the internet daily while I can easily leave home without my phone and not think anything of it.
@@Halapep They mean you can do anything with it, sometimes it is difficult to know what to do. For example, if your parents are poor and there is only one industry in your small town, you know exactly what you are going to do with your life, its easy. But if you are handed a million dollars and you can travel anywhere in the world and do anything, now its difficult to choose what to do.
@@Halapep open= endless possibilities. Like make what ever you want. OK...uhhhh like what? Like anything....hmmmm. ok. I spent several years almost buying a 3d printer and I just couldn't think of much to do with it. And the quality of the prints I saw were just not good enough fpr the cost. Bambu solved that barrier. The A1 is so cheap and so good, I can't loose. I am just kicking hobby ideas around now. Once I get a few things I want to post online, I will definitely use Slant 3D services and set up an online store.
One of my friends wants me to 3D print replacement knobs for an old stove. I was worried about how I would do the connection to the rod and the compliant mechanism may just be the answer I was looking for. Thank you
An oven knob is a poor use case for this idea. Oven knobs need to have a smooth non-porous surface so they can be wiped clean. Raw FDM surfaces are incompatible with kitchen hygiene maintenance requirements. Even outside the kitchen, I don't want knobs that accumulate hand grime. Those bright yellow knobs would end up looking gross. This is coming from someone who has been 3d printing since the Cupcake days. FDM rocks but has limitations.
I had a similar problem with Delta bathroom fixtures. They has a special metal spring inside. Once the spring broke, I found out they didn't make them anymore. So, I simply design a better 3D printed part.
@@schmi146 with heat inserts you can first print them all and then in one go, at a moment it's convenient for you, put the heat inserts, while in dropping the nut you have to do it one by one as it every knob is printed
I don't think you'd gain a real time-advantage using heat inserts. You realistically don't print just a single knob, depending on size you can fit probably like 30-40 of them on a plate. Dropping in 30-40 hex nuts at a time seems alot more convenient to me than having to worry about keeping the knob straight while pressing in a heat insert
I still say having a knob for a drawer would be better off with a metal insert since that tends to be stronger than just plastic.. but definitely easier to customize with printing

Knobs in general are under appreciated. You never really think about how much thought goes into the design until you get a bad one.
Current 3D printing development moved forward cause Joseph Prusa needed knobs for his music equipment.
1:16 why is your fusion360 in French ?

@@gullenator1 its much cheaper than injection molding or machining tho
@@L0wiee-ytthat fully depends on the geometry and how many parts you need. If you need tens of thousands, nothing will beat injection molding
@@OleBrouer yes, but we are talking about few pieces
@@L0wiee-yt in that case, yes, 3d printing can be cheaper.
Love this idea for 3D Printing. Another one is pool cue joint covers. I’ve made several of these knobs and caps like this.

Great.... Plastic knobs
Remember - print knobs, but don't vote them into office.
I've made a few replacement knobs for people, bbq, air fryer, drawers, and even one for an old car with a manual AC lever.
Always great info! Thank you!

A while ago I made knobs for my baseboard heaters because the original ones were so worn you couldn't tell what setting it was on
""...where the shelves MAKE the product." THAT is the wonder of the age we live in.
I like the oven knob but i need all the temperatures written on the knob to be compatible with mine
And now you can do multicolor for the location indicator
I've played with this a while, I like to pause print and place a stainless nut in. This creates a higher quality product.
For you at home it is fine. But think about to make 1000 😅 boring expansive task with human

3d printed knob for oven? Burns in 1 min.
if the knobs on your oven are getting hot, then you're doing it wrong (and most are already plastic anyway)
You need a new oven I think
