This is a solargraphy camera I designed

Pretty sure it's too big and unpractical, but I still made it.

Dimentions and info:

• Designed for 120x180 mm paper sheets. I used fomaspeed N311
• Focal length (the distance between pinhole and paper) varies from 60 to 180 mm. To do that, you attach the paper to a sliding focal plane and insert it into the grooves inside the camera body.
• For pinhole you'll need a 45x45 mm piece of soda can metal and 4 M3 screws
• For lid you'll need 9 M4 screws. Also I designed the lid to be loose so that a silicone gasket can be inserted into the gap

All pinhole cameras I make share same pinhole frame and wall mount profiles.
The simplest wall mount I made: https://www.thingiverse.com/thing:7316430

Feel free to use it!
