This 3D printed tube allows to connect microscope to camera that utilizes Fujifilm X-mount interchangeable lens mount to make photos and videos of things you see under the microscope.

Cool property is that there are no glass lenses within this adapter, and yet it works. It is based on observation that when camera body is held at approximately 40 millimeters from microscope ocular, image is projected and focused directly to camera matrix. Microscope itself acts as a tiny projector. Focus is adjusted as is usual for microscopes, by changing distance between sample and primary lens of the microscope.

To eliminate unwanted light passing directly through the case of adapter and also to eliminate light reflections within adapter interior walls it is wise to print this adapter from dark and matte material. Alternatively, it can be painted black and dark tape can be applied to exterior of adapter.

Here are sample photos done using this device.

Note: Fujifilm camera by default might refuse to make photos because electrically it does not sense any attached lens. This can be fixed by choosing "SHOOT WITHOT LENS" option within camera settings menu.
