pinhole135 camera mini

This pinhole camera is my first 3D printing design work :3
It has 24mm focal length and use standard 135film to shoot 4x6 full-size photos.
The pinhole size is suggest to 0.2~0.3mm around, and the angle of view is 84 degrees.

Details:

This pinhole camera is tiny and easy to bring. You can see I use some black tape to tie up the film, camera body and the back cap.The edge between camera parts are also tied up to prevent the light goes in. The cap is just glue up and also need to check the light can go through or not.

The shutter part is the key in this camera and it's very small. I suggest to use 1.0 density printing parameter and about 90% width because we need the shutter to cut out the light perfectly. Or you can put on some tape to make it stronger.

I use two films, one is the new and another is empty. I paste them together. On the new film, I paste a small plastic chip and its peak is located on the hole on the film, just like the pictures in the gallery. When you spool the film, you will hear the click sound.8 click is about a photo's length go pass.

I'll put on the photos shoot by this camera in the future.
Enjoy it! :D

I adjust the shutter design and the cap's shape.
It will help you for preventing the unexpected light exposure.
Try it:D

I put on some photos. @@"
It seems that the first shutter and camera's cap are not good.
Use the fixed one can be better.
I think I should use more black tape to prevent the unexpected light@@"
