The pinhole camera is a common experiment to showcase how old cameras (non-digital ones) work. Light is projected through a tiny hole at the front onto a translucent canvas. This video explains better how this actually works:
The two main parts need to be printed in black filament, while the projection canvas should be printed in translucent filament. If you don’t have translucent filament, you can also just use translucent paper.
For assembly, the projection canvas is glued to the inner side of the pipe without the tiny hole. Alternatively, you can replace it with translucent paper. After that, just slot the pipe with the projection canvas into the one with the hole, with the projection canvas facing the tiny hole.
For use, I recommend pulling the inner part out by about 5 cm. If everything works correctly, you should see everything upside down when you look into it. Make sure you are in a room with plenty of light.
