The Open Reflex, a research about desktop 3D printing, open design and hacking.
100% Open-Source ! Fell free to copy, understand, improve then share again !

The OpenReflex is an Open-Source analog camera with a mirror Viewfinder and an awesome finger activated mechanic shutter (running ~ 1/60°s). What's more, it's compatible with any photographic lens.
All the pieces easily printable on an recent RepRap-like ABS 3D-printer without using support material ! Everything should print in less than 15h and anyone should be able to assemble it within 1h.
All parts are separate ( Film receiver, Shutter and Viewfinder ) to simplify builds and modifications.
The source files are available under the CreativeCommon By-Sa license, fell free to modify them if you want a new feature, and don't forget to share your improvements here. ;)


All the detailled step by step instructions are on the Instructable : http://www.instructables.com/id/EEMGLJMHI3TRG33/

Note : In alls the files their is some .rar pack and the .Blend source. ;)

Enjoy !

Also are the pictures very good and can you download the pictures onto a computer or something

What is the size of the largest part

Hi tried this someone with M42 lenses and where i can get the mount

I'll make it as soon as I make my first 3D printer, it's very cool. Just wondering, why do you have black and white pictures ?

so if i wanted to print out these files and assemble it AS SHOWN HERE, what kind of lens/mount would I need? Nikon, I see. But what MOUNT?
ANd if i wanted a Canon EF mount, how would I find/make that?

Nikon SLRs have had essentially the same mount for ~50 years. Any older Nikon lens with a manual focus and aperture ring should work. Newer lenses often have no manual control over aperture size, which is a problem for a full manual camera such as this one.
There are adapters for Canon EF to Nikon F mount, and they vary from a metal plate (cheap) to adapters with onboard electronics. Googling the type of conversion you're looking for should pop up the proper results. Bear in mind that this camera does not support the electronics, so you only need the most basic of adapters.
(I realize it's been 8 months since your post, but hopefully this information is still helpful)

"An Excellent Camera."

-Chef Excellence

IMO: Don't waste effort in printing a lens. Concentrate on a lens mount for a specific manual lens. For example, there are tons of otherwise useless, very handy Canon "FD mount" lenses. If you go with Canon choose carefully. FL and R mounts are too old and harder to find. A Nikon fan here can recommend the manual Nikon mount most abundant. In designing your wonderful camera I would concentrate on two things. First, keep the focal plane as perfectly flat and perpendicular as possible. Second, Make the film transport as carefully as possible so the film is guided (hopefully) mainly where the sprocket holes touch the camera to eliminate the possibility of scratching the emulsion. Don't worry how it looks on the outside- makes for a more unique camera. Good luck! What a great project!

Simply amazing! Keep up the good work!

Really awesome project. I'm working on a 3D printed lens now (mechanicals only... at this point). Would love to contribute that to this project when things get a little further.

Where can I buy the light spacer that you mentioned in the Intractable?

The light spacer ? Which step ?

Step 3. The flexible piece that lets light through when pulled across

You'll have to cut it with an laser cutter or an vinyl plotter at your local techshop. ;)

I had forget to upload here the file, it's the "shutter.svg"
I cut it on 0.3mm black PET sheet, this kind of plastic is the one use for plastic spacer for exemple. I get mine in this kind of stuff : http://csimg.webmarchand.com/srv/FR/2800284604081/T/340x340/C/FFFFFF/url/trieur-a-aclastiques-plastique.jpghttp://csimg.webmarchand.com/s...

Ok, thanks. I have every other part printed out and assembled, this may be a sticking point though... I'll figure it out.

What's next, a movie camera? lol

Cool. I've got that exact lens in a box in storage from my flim days. Very very cool project.

There's no limit for Imagination & 3d printing. ;-)

This is absolutely brilliant! Thank you so much for sharing your work.

holy crap... coolest thing i have seen yet

that is nuts! great job!

Thx for all your greats comments. :)

are all of the components on the inside 3D printed, or are they from a camera??

Just the lens you have to get and a finger-skate truck [ http://www.closeup-fingerskate.fr/closeup/shop-produits/trucks-and-wheels/http://www.closeup-fingerskate... ]
All the rest is screw, plastic and a small bathroom mirror.

Super cool! Thingiverse is a better place with uploads like this! Way to go!!

Pure awesomeness.

This is so pure awesome. It took all of my effort to keep myself from printing this because I've already said my goodbye to the world of film, darkrooms, and chemicals. Nice job.

You should not ! Darkrooms and chemicals are fun ! :)

This is beyond amazing! Thanks for sharing!

Greatest thanks and appreciation to all involved in this projects successful arrival here. This, and projects like it are doing immeasurable good for people everywhere!

Léo! Your work is totally inspiring! It is a joy to see how you combined good old analogue photo technology with modern 3D printing.

Thanks for sharing this with the world on a open source license! It will for sure infect others and inspire them to work as you do.


I think there are some features here that are very clever, and I like the modular approach you took. For instance, putting the viewfinder ahead of the shutter. I was trying to come up with a good design for a secondary shutter which wouldn't take up too much space, but it looks like you've done so here by using a focal plane shutter. This shutter also gives your camera a really interesting shape, and so I love this design for that.

That's so great! Thanks for sharing it!!
