I wanted a solution that doesn't add any height to the original lens cover when the ring light is mounted on the microscope, that looks sleek and is easy and clean to print, even in draft mode.

Check your original lens cover before printing. It should have a top opening of 55x25mm. I have seen slight variations depending on the microscope manufacturer. I designed my cover to fit my Swift branded stereo microscope.

Use the original lens cover screws for attaching the adapter to the microscope.
