Fujica X-mount (circa 1970s-1985, not to be confused with the confusingly similarly-named 201X-era Fujifilm X-mount) to E-Mount (Sony NEX, A7/r, A6000, etc) adapter.
Based off measurements made from the 3 Fujica X-mount lenses I have (all 3rd party, one Rokinon and two X-Kominar) and my Sony A7 camera.
I'm not sure how well the measurements adapt to allowed manufacturing tolerances for either mount given the limited amount of samples, but it should be easy to modify the OpenSCAD source to match if you run into fit issues with the current values.
There is no explicit locking mechanism on the Fujica X-mount side, but between the tight fit of the thread rings and the aperture lock, this hasn't been a problem for me. When printed with high-infill in ABS the adapter has been working out really well. Use caution if using this with highly valued lenses.
