Summary

I recently bought the Andonstar V160 USB microscope and it works basically well, but there is one disadvantage. The built in LED illumination applies very hard light and causes adversely reflections, especially on metallic surfaces.
Therefore I decided to print a small light diffuser for improving image quality. It is made from transparent PLA and it includes a 16×2.5 mm o-ring seal for sticking it on the plain microscope body. I added two images with and without the diffuser where you can see the differences.
