This adapter should hold the microscope lense in the exact center of the 1x / 2x camera lense which is the better one for the microscope.
You can easily slide the adapter and the microscope off and on. Nothing wobbles on my part.
I did construct the microscope adapter atop of a Pixel 7 model that I found als CAD file. It should perfectly match your phone if printed with the correct amount of flow.
I hated the clumsy clamp of the cheap Apexel 200x microscope. You have to center it all the time. It did cover parts of the phones screen and did clamp very stong. With this simple adapter I am more than happy to use the lens and want to share that with you. :)
