OM to EF mount adapter: Olympus Zuiko 50mm f1.4. 3D printable STL file.

This is an STL file of an adapter specifically for the G.Zuiko 50mm F1.4 to EF mount. The adapter is not the flimsy kind that you thread on. This is a replacement flange where you remove the annoying center black ring, and the flange with the two buttons and you replace it with this flange using the same screws. It is calibrated to focus at 450mm to infinity. Remove the two silver flange rigs shown in the last two images and replace them with this flange. Make sure the protruding leg slides along the spring loaded aperture switch lever which is the black one. There is also a silver lever that is just for opening and closing the aperture, just ignore that one. As you install, you have to rotate the flange to the nearest screw hole clockwise.
