Microscope from Camman Childrens binoculars V2

This is V2 of my microscope. I've been using this for about 3 years and it's worked a treat. I made the following improvements:

- Changed the mounting system to be GoPro compatible
- Added a ledge for the bottom lenses
- Added mounts for 13mm diameter pen lights: https://ae04.alicdn.com/kf/S32108b3c08d54453ac6e0dfc5a7b7f7e3.jpg
- Updated the design so they focus 115mm away from the bottom lenses where I found it to focus most clearly.

The torch beams can be used to set the ideal distance, when they overlap evenly on both sides the microscope is in the best focus.
