My PCB microscope had an LED light that mounts with screws that drive into the outside of the scope which I didn't like since it can damage the scope housing.  I decided to model an adapter to get a tight fit around the scope housing and provide better support.  I'm not sure if this works with other microscopes but it works with my Tomlov DM-702 Flex-S.  I've included the f3d file also in case anyone wants to modify the dimensions to fit their scope.

You will need the following:

• 3x - 3mm, 12mm length socket head screws
• 3x - 4mm, 12mm length button head screws
