This is the Tilt-O-Matic - a 3D printable tilt-shift adapter for using 35mm lenses on mirrorless cameras. There's a more detailed writeup on my blog here: https://bhautik.org/the-tilt-o-matic-a-3d-printed-tilt-shift-adapter/
In this iteration of the design the lens-side accepts any Canon EF-lens and on the camera-side mounts to a Fuji-X body. There is no electrical connection so any attached lens is completely manual.
The design could feasibly be adapted for most full-frame 44-45mm registration distance camera lenses (e.g. DSLR-style camera systems such Canon-RF/EF, Nikon-F, M42 mounts etc) and on the camera side most APS-C or smaller sized mirrorless sytems (e.g. Fuji-X, Olympus PEN, Micro 4/3 etc).

To build this you'll need 4x of midBodyPlatePin; the rest of the build is pretty straightforward and you should print with as fine a resolution as your printer can manage (worked great for me at 0.1mm).
