The file 'Nikon Pinhole Lens 3D Printer Model' is (stl) file type, size is 309.2KB.
A pinhole lens for your Nikon camera. Focal length is 50 mm, f-number should be around f/150, but depends on the size of your pinhole. A good calculator can be found here.
To prevent light leakage, print it in a dark material, line it with tinfoil, or paint it black.
Because your printer will not be able to print the sub-mm pinhole, it has to be made from tinfoil with a needle and glued inside. There are many guides online on how to do this.
