If your Pen (35mm) SLR has a broken eyepiece like mine did, this 3D printed part is the perfect replacement to make your camera look like new again.
Note: This is NOT compatible with the Pen F. I'm not sure about the FV, I don't have one to test.
Taking the camera apart to replace it is fiddly, but doable with a screwdriver and some patience. Here's a guide if you want to take a look at the process: https://docs.google.com/document/d/e/2PACX-1vQuDWOO7Hgq7Xh2aybMG77dnx8ZbR6LR264nkOhLlx5HkOA5rVGJceWVST3whnMSOt88zx5SSM11pZo/pub
These replacements are based on measurements taken from an original part, and fit the camera with no modifications. They are 3D printed in a tough resin, which is then clear coated for gloss and durability. They should also be compatible with my cold shoe mounts, or the OEM part from Olympus!
