Update 04/07 : Just upload an fully monted picture and my work file with all the SolidWorks Files.

Here is my second version [truly printable] of the 3D printed pinhole box !

On the picture of 3D printed part it's all the test and fail print I do before I have an good one, the final parts are on the front.

The pictures are my first test film, taken with this printed box.

Sorry for the short description, I haven't time for the moment to write an real instruction notice.

Print all the part, bobine two time.
Build your own pinhole or buy one.
I buy mine at stenocamera.fr (use 0.26mm pinhole) but you can easy buid your own, there is a lot of tutorial on the web.
Glue your pinhole on the center of the BotierB part.
Glue some dark fabric on all the part that will be in contact with film, and on the inside of boitierA et boitierB, the top of Bobine et under the Bouchon.
Fix an hexagonal screwdriver head on the bouton part for pull the film.
When it's done you can assemble all piece with ruber band.
(sorry I haven't picture fully assembled, I lend my copy of it for summer before take some...)

You can use this pinhole box with both film or photographic paper
For the expose time you can use this little sofware for conversion : http://www.pinhole.cz/en/pinholedesigner/

For the rest your alone, I'll work on a true description with pictures and an real corected english on in september.
I'll upload the design file (SolidWorks) as soon as I can.

If you have some questions do not hesitate to ask.

For commercial use please ask me before.


Imprimez tous les éléments en 1 exemplaire, sauf Bobine.STL en 2 exemplaires.

Pour une meilleure étanchéités lumineuse utilisez un profil d'impression avec au moins 3 passage pour les contours les épaisseurs transition.

Une fois toutes les pièces imprimés collez sur les surfaces servant de joint un peut de feutrine noire ou du faux velours noir autocollant pour améliorer l'étanchéité. (cf : Photo)

Dans le trou du bouchon enfoncez un embout de tournevis qui correspond au trou de votre pellicule. (cruciforme pour la plupart)

Fabriquez (ou achetez) votre sténopé (le trou).

Il est temps de monter votre boitier.

Etape 1 : L'objectif.
Placez votre sténopé dans la partie prévu à cet effet dans l'objectif, vous pouvez le coller de façon définitive ou simplement le placer en force.
Placez ensuite l'obturateur par dessu sur le pivot prévus sur le pivot prévu à cet effet.
Fixez l'ensemble en vissant le capot au dessus à l'aide de 4 petites vis M3 (les mêmes que la MakerBot)
Montez votre boitier à l'aide d'élastique,
Commencez par mettre la pellicule dans les rouleaux , puis le dos et enfin le bouchons.
Pour le défilement de la pellicule si le dos est bien serrer (mais pas trop non plus) vous sentirez quand elle sera amorcée.
Amusez vous !

can you list the dimensions of one of the objects, because when i open the stl. file in rhino to print, im getting crazy large dimensions of the individual pieces (from 40 inches to 90 inches). anyone else have this problem? but if you just share the dimensions i can easily rescale everything according to one measurement. thanks!

I'm printing this out now. Will upload pictures when I've made more progress.

Nice !

If need more explication don't hesitate to ask.

If interested, next I'll work on a smaller version, for only 1 picture on photo paper (long exposure) working with an Ikea cooking timer that would control the obturator. Mutch shorter to print that i could easy multiply.

this is great! what program did you use to design it?

I use SolidWorks, I'll upload the designs files tonight with an fully monted picture. (I hope)

Absolutely awesome!

This is freaking awesome. I was thinking small by starting to design a tilt/shift adaptor for my lenses, this is great.

Thx, If it can help. ;)

The goal of this box it's that can be easy changed.

The front part can be easy changed for use an different focal or adapt an real lens, the film box are the same.

For exemple, I'm looking now for an old camera with an shutter on the lens (as on most of folder camera) and adapt it for use on this box.

This is great, I am so impressed

Do you have a photograph of the completed assembly? I think that might be very helpful for some of us.

I forgot to take some and I lend the final print to a friend.....

I ask him to send me a picture of it but I'm still waiting.

I'll try to upload an assembled CAD preview in the evening.

Here it is, I hope I'll help. ;)
