Pinhole for Nikon Z-Mount

thingiverse

A pinhole "body cap" for Nikon Z-mount. The printed parts are just the holder for the actual pinhole, you'll have to make one or buy one on Ebay (I got mine from fireseller66, a .15mm). Printed in black PLA, it's completely light tight even with sun shining on it directly. Mirrorless is pretty ideal for this, since the short flange distance makes for a nice wide-angle view (as opposed to a DSLR where the pinhole is too far away from the sensor). For Nikon Z-mount, you end up with about 17mm of focal length and an equivalent f-stop of around 128 (if you use a 0.15mm hole). You can easily frame your image using the viewfinder, use the histogram and level, and even IBIS! The printed parts hold together pretty well by themselves, but I glued them anyway to avoid them coming apart. I went a little overboard with the little white dot, but since I was printing the disc separately anyway, it was pretty easy to insert a filament swap to get it printed in a different material (I've posted the gcode for that [on another site](https://www.prusaprinters.org/prints/2446-pinhole-for-nikon-z-mount/user-gcodes)). I designed this in OpenSCAD, the file is included. Sliced in Slic3r with the Archimedean spiral for the top and bottom layers (after separating the objects) to get a nicer finish.
