Adapter đèn vòng (Ring Light) cho kính hiển vi (Microscope Ring Light Adapter)

I recently bought a microscope for some fine soldering (SMD and such). It came with a ring light which can be clamped onto the lens of the microscope.

I didn't like this method of screwing bolts into the side of the lens, so designed an adapter onto which the ring light can be attached. The adapter itself can then be pressed into ring mount.
