Introduction: Laser Cut Foldable Wooden Glasses

About: I'm a fanatic of self-fabbing!

Needed tools and materials:
 - a CO² laser cutter
 - plywood (3mm - 1/8”)
 - the current instructable


For those who are in a hurry (yes, it happens! :-):
 - download the project at your preferred format (EPS, AI, SVG, CorelDraw, PDF)
 - the settings are fitting Epilog laser machines: thin lines are cut, there isn't anything else here
 - assemble the part in accordance with step 3
 - enjoy!


Caution: the uploaded design is for children (4-6 year-old), so if you want to make it suitable for an adult or if you want another customization, the others steps may also be useful.


Step 1: Context: Background and Motivations

There are already lots of DIY wooden glasses available on the Net, but I always found some limitations:
 - either they are too simplistic and not functional enough (cannot fold the stems, see: http://www.thingiverse.com/thing:1345)
 - or they are not 100% out of wood, with metallic hinges for instance (see https://www.instructables.com/id/Wooden-Glasses/)

It’s just a matter of taste, but I generally prefer designing objects with no external accessories or as few as I can, even if it can lead to a (kind of) suboptimal implementation.

I also recently found an interesting (100% wood) idea here: http://thelasercutter.blogspot.fr/2012/03/snij-glasses.html
But the latter implementation makes it difficult folding the glasses to put them in a pocket...


Step 2: Explanations


Well, I felt forced to consider designing them on my own laser cut wooden articulated glasses, great!

I studied how usual (metallic) glasses hinges were designed to try and replicate these my way.

It came out naturally that the stems and the frame would be vertical parts, whereas hinges would be cut horizontally. (Don’t hesitate to comment this below if you don’t agree!)

The challenge was also to joint the hinges with the stems and the frame in a way that would be as elegant as possible: not too big, but sufficiently robust to make the glasses useable.

Step 3: Result: We Design Them Basic, You Fab Them Special!

So, finally, the frame and the stems are really simple and basic.

The only tricky parts are the way the hinges are mounted on the stems and frame.

The result can be seen on the photo.

If you want to customize them for another size or shape, you'll just have to modify the frame or the stems; change the hinges at your own risk ;-)

Anyway, improvements are welcome!


For mounting instructions, follow the photos and the order (annotations).

Step 4: That's All, Folks! Now It's Up to You!

Well, that's all, post your comments and questions.

I put here the design files in several formats, I hope it'll be sufficient:
 - CDR (CorelDraw X4, original file)
 - SVG (exported but successfully opened with Inkscape)
 - PDF
 - PNG
 - AI

Hello r4f,
these glasses i've cutted in Medium-Density Fibreboard. It's not the most beautifull material there is, but almost the cheapest. I used it for testing your design.
Now I'm going to tweak the design a little so it fits an adult head. I might change the shape a little as well.

So great from you, Markuzz! You did it! Thanks a lot!

I often use MDF myself for making things, since I have my own laser.

In fact, there are 2 kind of laser makers: the ones who use MDF since they don't pay for the cutting time, and the others who use ply since they pay for the cutting time.

Explanation: plywood is 3x more expensive but 3x quicker to cut...

In fact, I lost the adult-size template when I tweaked it to fit my son's head, which explains why the last I published was the smallest version ;-(

Customize it, you're 100% right! Once again, please post your customized photos here!

"I design them basic, you cut them custom" (cf.: http://www.propagandaemrevista.com.br/fotos/19941201_capricho_levis_h360.jpg)

I have my own machine and like using ply because it looks nice... and stains well...

Though MDF has a lot of really nice qualities as well.

Brilliant and highly adaptable design! I see several techniques here that I've not seen before in laser projects, including the grippy zig-zags and the constrained 3-layer corner joints. Did you also glue any of the pieces together, or is it unnecessary? Thank you for posting your files.

Hi audiolizard,
Really flattered by your kind words!
I began posting my works on Instructables when I designed these glasses... I knew they were cool ;-)
Nothing is glued at all, that's how I prefer to design objects when I have the choice.
I've posted a few pictures of another cute design on my Pinterest board, here: http://www.pinterest.com/pin/255720085065067332/
No moving parts, everything is static but I like it also; one could qualify it as lasercute!

Elegant and fun! You should upload these to Ponoko or some similar service so lazy people can order them!

SOME BODY CAN TELL ME A WEP SITE TO DONWLOAD PATRONS FOR LASER CUT

Nice Job, thanks for sharing! I am going to use this system for an eyeglass I am designing. In your opinion, do you think this would work with acrylic? If not, what other material, other than wood, would you recommend? Than you

Hi @nestorApestana! Thanks!

Don't forget to post pictures once you've done yours!

The design would certainly work with acrylics, but things may have to be adjusted, like the "grippy zig-zags" as @audiolizard called it (see in the above comments).

If you have sufficient power, stainless steel would certainly work, too! :-)

Personally, I prefer wood (generally plywood or medium), but it may also work with cardboard...

Cheers,

Raphael

Thank you for the quick reply and I will definitely post pictures once they are done.
All the best,
Nes.

Alright, Nes, it's a pleasure to share about my own creations :-)

Keep up posted!

Hi KDE!

Great, I'm happy you like them!

Just be careful of the scale, since I don't remember if the downloadable model is for adults or for infants! I you scale it up, be also careful on the assembly part that should not be scaled at all...

Hey petit-mouton-violet, thanks for watching!
At the end of the article, you'll find the download links to the files; they are named laser-cut-foldable-wooden-glasses (with an extension which depends on the file type pdf, eps, ai, svg or pdf).
If you're French-speaking (you may, I guess, with such a name ;-), have a look at this: http://www.pinterest.com/letsfabit/formation-design-laser/

Hello!!,
Thank you so much for your help!!! I appreciate you taking the time to respond. I am actually, spanish-french-english speaker :) I am having trouble finding templates for adult glasses in Illustrator. I am making several gifts for friends and I have no clue on how to take measurements to make them.

I f you could tell me how to do so, or any other link I could see?
Have a nice day :)

The key measurement I took into account were:

  • width of the face (equals the length of the facing side of the glasses)
  • distance between the point-of-contact with the nose and the point of contact with the ears (for the spectacle arm)
  • width of the nose between the point-of-contact with the spectacle frame

But the easiest way is to take measurements on a pair of glasses that you already own...


Hey togo1919!

Don't forget to post some pictures (comment + "Add Images") of it & click on "I Made it!" (upper right corner as far as I see on my screen) to tell that it's working!
