Reverse adapter Nikon F-mount to 52mm

thingiverse

This is a reverse or retro adapter to mount a normal lens in reverse position for macro photography. The adapter mounts to a nikon f bayonet mount on the camera side and a 52mm filter thread on the lens. Printed on an elegoo mars resin printer. FDM machines probably won't be able to print the finely pitched threads. It might be possible to replace the thread section by a glued on UV filter or something similar. Two versions are provided, the 35mm adapter is longer, so works like an additional extension tube and provided further magnification. This however comes at the cost of a tiny focus depth. The other adapter has a spacing of 13mm. I have also uploaded the stl file for the Nikon bayonet mount, as it took me a lot of tries to get the dimensions right maybe this helps somebody for their own projects.
