This is how I designed 3d printed frames around lenses that can be made by any optometrist!

I replaced broken my broken glasses by 3d scanning my lens using my phone's camera and Autodesk's 123D Catch. You can see the instructable here: https://www.instructables.com/id/3d-scanning-a-gla... , but you can order lenses from a variety of sources and download 3d models to design around. Check out http://www.eyewearkit.com/ for a place to start.

I used the 3d scan of my lenses as a reference to design my new frames in Rhino. This will require some moderate 3D modeling skill, but the process can be applied to almost any 3d software and can be very simple.

Step 1: Importing and cleaning the 3D file

If you are working with a downloaded 3d file, much of this wont apply to you, but may come in handy to know.

Since I am working from a 3d scan, I have to start by importing my 3D scan and rotating it so that is in the right orientation. You can trim off the excess mesh around your lens by drawing a closed curve around it and using a mesh split.

Next scale your lens to the right dimensions. You can either measure it with calipers, or look at the inside of your glasses to find the sizes. The first number is the width of your lens, the second is the distance between lenses, and the third is the length of the arms.

Move your scan so that it is offset from the origin the correct amount. Since glasses are symmetrical, you only need to model half of them.

<p>Hi Aaron, can you please send the file to my email? Informacoesdinheiro@gmail.com</p>
<p>Hey Aaron - nice Instructable. What I'd like to see next is: instead of relying on existing frame styles . . . how about scanning each individual's head and REALLY custom designing a frame fits the structure of your head/skull perfectly?? Maybe they don't even have to sit on the ears. And the lenses can be contoured to the exact structure of one's skull/eye sockets. Lenses could also possibly wrap around your head so you can see better in your peripheral vision. </p>
<p>Hey Aaron, great job!</p><p>I have been trying to print a few frames but the hinge section always ends up breaking. I do not want to use a pin to join the temple and the frame. Any recommendations as to how I could solve the hinge issue</p>
<p>The website of eyewearkit seem to be offline for some days. Do you know an alternative?</p>
<p>Now we just need a wiki where people can upload the 3D lens models for many different kinds of lens. Then we need to figure out how to adjust the designs for the variable features of the face (the distance between eyes, heights of ears, bridge of nose). I have no doubt that printing lenses will soon be a thing if it already isn't. <br><br>I think fitted glasses should be considered a right of the people and not something people should profit from--just imagine the impact cheap fitted glasses could have in the developing world. Increased literacy for one, but also less ocular headaches and migraines. </p>
Start it here! I just ordered replacement lenses for some Ray Bans so I'll upload the lens models when I'm done. If there's enough interest we could start a wiki!
<p>I agree, it's been 6 days since you commented have you found anything like that? I'm trying to make one that fits to a friend of mine, :D will upload when I finish </p>
Not yet, I am excited to see how it goes!
<p>this is really cool</p><p>i'm going to give it a try.</p><p>What material did you use to make the translucent frames?</p>
<p>The translucent pair is printed in &quot;vero clear&quot; resin from a connex 500 printer.</p>
I've had to wear glasses my whole life and think it would be fun to make custom frames. I'm curious to know how much of each material you needed for the project, and what was the blending ratio for the arms?
<p>Im not sure what you mean by blending ratio. Can you explain?</p>
<p>Great work, this might be a cool idea for my middle school stem students that are learning to use autodesk inventor.</p>
<p>Thanks! I think middle school students would love some custom specs!</p>
<p>Hi, my name is Matej and I come from Slovenia, and for my bachelor degree I am making 3d printed sunglasses. And I love you tutorial, it is very helpful. But I would like to know where you had some problems (and how you solved it) and if you have any material I can use (beside your tutorial).<br>Thanks</p>
<p>The only real problem I had was the hinges breaking under too much stress. If they were printed in a vertical orientation, it would probably help a lot. Sorry, I don't have any other documentation other than this.</p>
<p>Great stuff Aaron!!!. It must have costed you a bomb to print it rather than buy. </p>
Thanks! I was actually very lucky to print these for free at Autodesk + Instructables' Pier 9 workshop as an artist in residence.<br><br>Still, printing a pair on a makerbot will cost nothing compared to buying new frames.
Thanks! You're a legend!
<p>Nice one! Thanks for sharing! Any chance you could share the rhino file as well? Nice work!</p>
<p>Thanks! Sure, I've added the rhino file to the last step. </p>
<p>I guess if you didn't have direct access to a 3D printer (like me), you could send the file off to a company to 3D print it for you. Maybe a little more expensive but if you can afford a printer upfront its still an option. Great instructable and thanks for including all your modeling files. :)</p>
<p>Thanks! It's true, some printers now aren't much more expensive than some high end glasses. A nicer print in SLS or polyjet will be more pricey, but you can find someone nearby that can print for cheaper. Try 3dhubs.com </p>
<p>it is cool</p>
<p>As an update, it's very possible on a makerbot. My first print was 0.5mm too small, but with a little calibration it would fit perfectly. </p>
<p>I broke my frames last year. My eyecare place didn't carry the replacement frames. I wish I had a printer to make a pair. Still have the lens.</p>
<p>I hot glued my old lenses into frames from 3D glasses from the movies. They look ridiculous, but work very well. They are my tv watching glasses!</p>
Rather have access to or know someone or company that can print me a new frames. Best thing about it? I can tell people that there are peaceful uses for a 3D printer; other than producing weapons. Hey! New frames! Not from LensCrafters!
<p>Sounds like someone needs to start a company 3d printing replacement frames...</p>
<p>Love it</p>
<p>Thats a shame, and one of the big problems that 3d printing has the potential to solve. If you have the time, check out http://www.3dhubs.com/ to see if there is someone nearby you with a printer. You can also try one of the larger services like http://www.shapeways.com/ or http://i.materialise.com/ .</p>
That's for the heads up.
<p>this is amazing, keep up the good work.</p>
<p>I love this! I'm always losing my sunglasses, so I buy the cheap ones, which means they get broken... It's a vicious cycle. I would love to take my $10 Wally World polarized fishing glasses and make some arms and hinges that would actually last me a while longer. I'll second the &quot;shoulders of giants&quot; comment from Wilgubeast!</p>
<p>Thanks! I'm planning to do the same. You can even order replacement lenses for most high end sunglasses if you want to design your own frames around those.</p>
<p>This is a great idea. I really don't like the current fashions for glasses, and my glasses are getting pretty beat up. Time to model them up and print a new pair! </p>
<p>Do it! Thanks!</p>
<p>Great Instructable! Such a fantastic tutorial for making glasses hackable. This is one of those "giant's shoulders" projects that enables all sorts of other fun projects. I can't wait to see what other people can do with this, but I'll be happy just to see you around the pier with glasses intact. </p>
<p>Thanks! I'll try to keep them intact!</p>
<p>This is an awesome project! Since glasses are so expensive, you can put money in a 3D printer instead (maybe they will become cheaper soon)</p>
<p>Exactly. Thanks!</p>
