I use a Zeiss Axio Imager microscope at my job. It has a mount for a camera, but I don't have the camera. I sometimes need another person to read some slides for me, but they are not always available to come to my location. I was sharing images with them by holding my phone over the camera port, and decided I could make something to hold it for me. This mount is designed to put the camera of a Samsung Galaxy S10+ directly over the camera mount for the Zeiss Axio Imager microscope. This is my first attempt at making something with threads so the holder will screw onto the microscope.
