This is a 3D printed adapter used to take photos through a microscope. Several similar models are available on the internet but I found them to be designed either for a specific mobile phone or, when adaptable, to be very clunky, large or complicated.

This design makes provision for most phones, the width can be anything from about 55mm 90mm and the length is not really a limited since it is open at the top and bottom. I would estimate that the maximum thickness is about 12mm. The print is designed to handle off center cameras as well (in case you camera is centered to the other side you might have to flip the print which can be easily done on most printers.)

This design only have 3 printed parts, 5 screws and 5 nuts (nuts are optional in most cases since the screws holes are designed to be tight enough to get away without the nuts) Only one clamp stl is supplied, flip the "CLAMP" stl to print the second clamp.

An M3 screw is needed for the clamp around the microscope lens. Four M4 screws are needed for the 2 clamps to clamp the mobile.
