Thankfully the printers are free and cost no maintenance!
It's more that you have the capability already and can do many other things with it, already do other things with it. You're not going out and buying a Prusa just to print one knob.
I am now. You can't set my limits!
Your limits are 250 x 210 x 210 mm, see I just did it!
Don't be like me and instead decide that resin is the way to go for your first 3D printer because you have cats and the enclosed FDM options are more expensive basically just for the box.
Resin is great if you like inhaling toxic fumes (I print with PLA don't @ me about ABS lol)
That's not a huge issue as long as you follow the necessary safety stuff. Quality of the resin prints is extremely high at pretty low cost compared to the FDM printers I've seen. Getting near similar quality as resin seems to require much more expensive printers.
Of course you can deal with it, but it's a hazard I don't personally want in my home where I live.
Eh, depends on where you're at and what your place is like. I have a spare room that isn't actively used daily by anyone, so with my Elegoo Mars 4 it's only an issue when removing the finished piece and post-processing/cleaning the machine.
If it more effort? Of course. Does it actually mean much more work? Not really, just a bit more planning. It's only the liquid resin that's a fume issue. Even then, there's a powered fan/carbon filter that removes the vast majority from the air before it can even leave the machine. Then the piece cleaning just takes a few minutes in a sonic bath, and draining unused resin filtered back into the sealed bottle. After that there's no fume issue for any other post-processing like UV Curing that the piece needs.
Sure, if you can get adherence and leveling just right and buy all the tools and supplies needed for post processing after investing in the resin itself, which as an added bonus will etch any plastic on the machine it comes in contact with cause for some reason chemical resistance isn't something we thought of when we were picking out materials to make a resin printer with.
I couldn't hack it. This was my first 3d printer as well and I gave up on 3d printing as a whole a long time ago cause I couldn't learn CAD. Even if I did manage to do that, I'd probably have spent more time finagling with the machine itself than I would enjoying my prints. Nothing ever stayed fixed on that thing.
Probably my fault for going cheap (anycubic photon mono on sale for $100) and not doing my research, but it was firstly an experiment to see if 3d printing was even something I would follow through with long term.
Well DreamButt, your limit is apparently a disappointing butt.
I 3D-print my own glasses. I save a lot of money. Totally worth the time and effort.
How does this work? Like, can you just take them to an eyeglass place to get lenses put in them?
You have lenses made for the frames, which may or may not be costly depending on your prescription, but it's a one-off purchase until your vision changes and you need a new prescription. Then you print the frames and mount the lenses yourself. When you break the frames, print another set and hey-presto, 15 minutes later, you have new glasses and it cost you pennies.
I released all the files and complete instructions to print and build my glasses here if you're interested.
This is a great idea, no doubt! I will say, though, that my frame-buying stopped the year I bought some expensive titanium Mykita frames. I've replaced the lenses in them 3 times, because lenses wear out (usually from micro scratches).
The titanium is incredible; I've sat on these and they just keep going. But the other major factor is that the hinges are not independent bits; they're integrated into the frames and are clever little bits of springy... things. They don't need to be tightened, they don't wear out, and unlike all other frames I've had, they're not the weak point that breaks first.
These are more or less my frames - same basic style and construction - although newer and slightly different, the construction is the same.
If these frames ever die, I'm just getting another pair, and will happily pay the cost. These are BIFL products.
If you're happy with your frames, more power to you of course.
But there are two things my frames provide that no other frames have:
-
I designed them - and the clip-on sunshades that go on them, and the custom cases. There's something deeply rewarding about wearing something you made yourself - and also seeing other people wear them too, as two of my colleagues at work liked them enough to print them and start wearing them also. They're worth pennies in plastic but they're priceless to me.
-
As long as my lenses aren't compromised, I'm totally self-reliant. I don't depend on an optician's schedule - or that of their low-cost suppliers' in a developing country halfway around the world for my vision needs. I break, I make anew all by myself at home almost for free. That and never experiencing that sinking feeling when you sit on the couch and you hear that dreaded crunch sound is liberating.
I'm sorry. I think I conveyed the wrong message. I was more gushing over my BIFL frames than suggesting they are superior to DIY frames.
I can't change the style of my frames: you can. I can't easily adapt my frames to sunglass shades, as you point out. You could conceivably create frames with cameras in the hinges, or adapt them for VR, or just make a crazy pair of party frames in rainbow colors and an Elton John flair - I can not. If I had a 3D printer - and the patience to use one well - I'd be all over your solution. It has a lot of advantages.
I didn't mean to imply my frames are better; I was only saying that I'm happy to have found what are turning out to be indestructible frames that have outlived multiple pairs of lenses.
I’m sorry. I think I conveyed the wrong message.
Don't sweat it. I didn't read anything in your comment other than that you're happy with your frames 🙂 I was just adding to why I'm happy with mine.
That's very cool! Definitely a cool way to explore new styles, too!
Also, given I wear these almost every waking hour of my life and I'll be shit-out-of-luck if these break while I'm out and about, they're one of the last things I'd want to cheap out this badly on. Assuming you aren't getting high-end designer frames, you've saved $40–$60 at the cost of spending the next two years wearing a dinky piece of brittle, probably uncomfortable plastic on your face. Yay...?
No. My glasses are perfectly adjusted to my face - simply because I took the time to design them just right for me - and they're very light. They're probably the most comfortable frames I've ever worn.
They are not that flimsy. Granted, PLA or PETG aren't the most rigid or durable materials out there, but they easily match acetate. And if I break the frames, it just doesn't matter: I can make new ones in minutes. If anything, you're probably a lot more inconvenienced than I am when you break your glasses because you have to wait forever to get a new pair made, and you have to be a lot more careful than I am. Me, I just care about not damaging the lenses. But I can break the frames every day of the year, not have to go without glasses and I'd still come out ahead financially.
I didn't cheap out. I started designing my own frames 20 years ago (out of silver nickel back then) because I wasn't satisfied with the commercial alternatives. It took me a lot of time to come up with the perfect frames - perfect for me anyway. The cost savings are a nice bonus.
Don't dismiss 3D printing just because cheapskates use it to cheap out. Done right, it's a very nice alternative to mass-produced items - and you know as well as I do that there's nothing more personal and bespoke than a pair of glasses.
Any documentation of your work on 3d printed glasses somewhere ? Not for me just for a friend (o･ω･o) Edit : didn't see your comment bellow
Luxottica shills are everywhere!
"Luxottica shills" lol
Nah, monopolies like Luxottica can suck shit (although there are plenty of brands not owned by them that you can just as easily buy). Doesn't change that 3D-printed anything is made of cheap, relatively brittle material compared to easily affordable monel, titanium, and other metal frames. I can't speak to the durability of plastics manufacturers use versus what you would use DIY, but the metals have to be much more durable, and they consistently look much nicer than the 3D-printed ones I'm seeing online. Also, unless OP's are somehow way above the ones I'm seeing online in terms of quality, they're probably more comfortable as well; you can cope all you want that you painstakingly designed it to the contours of your face as much as I can cope that the t-shirt I weaved out of corn husks is better than that mass-produced crap because I tailored it to the contours of my torso.
It's cool, don't get me wrong, but this seems like one of the last ways I would try to cut corners financially.
It was definitely a tongue-in-cheek response to yours. FWIW, I mostly agree with you. I can also see their perspective, a 0.30EUR print + finishing time to clean it up (support removal, solvent vapor bath for smoothing, etc) and put the lenses in, even if they need to do this multiple times a year, still comes out cheaper than buying the frames, even if the quality is suspect. Plus, OP gets to wear their nerd badge with pride.
Personally, I've tried replacing EDC items with 3D printed versions and didn't have much success, but then again, I didn't invest too much time to rev the STLs I found or design better ones.
Do y'all like... Loose the knobs for your stove often?
I lose one every time your mom comes over. She's a real knob gobbler
Gottem
These knobs are usually painted plastic, so it's reasonable to think it got broken or something.
What are you having sex with it? /s
Plastic knobs are more your mom's thing.
Lmao gotem
Do you frequently damage things you have sex with? I think you're doing it wrong and are amazingly presumptuous with your tone considering you just made yourself the weird one.
Satire tag added
Edit: please don't downvote this person. I was wrong to not have included it.
How dare you
:3
My grandmother cleaned at least two of them to death.
If you twist them beyond their normal stopping point the thin plastic that holds the knob to the peg behind it can snap easily, or like if a curious kid slides it off the peg it they might lose it or it might not go back on very securely.
No, but I do occasionally lose them.
Then spray paint the fucker with matte metallic paint and bingo.
So that's why display models always look so fucked up
I’d use a high temp filament there to be safe
Not necessary unless your crotch is frequently aflame.

IF_TV has the right idea. not like theyre going to sell the floor model anyway
