Pinhole camera for phone

Using the mobile phone to get the the pictures directly from the camera, via projection on a screen in the camera.

6mm hole in the bottom that accepts regular tripod 6.35mm screw.

Can be printed without supports.

Instructions
1 Print all parts (maybe some extra c-clamps)
2 Glue c-clamps (if they work with your phone.
3 Make a pinhole. Ideal size according to https://mrpinhole.com/calcpinh.php is 0.42mm, I made a short video on this topic:

4 Cut out paper and glue it to the projection part.
5 Optional: Paint the interior black, the darker the better.
6 Attach camera, I used tape ;-). This is a tricky area with huge risks for light leaks into the chamber. Maybe some black foam would be the best?
7 Take pictures (use manual mode and long shutter times and fixed focus)
8 The pictures will be upside down and mirrored, fix this, crop and maybe adjust sharpness and exposure.
