well you know you can get top adjustable mirror mounts from Newport, they cost a bomb and are pretty big. well ive been working on a micro version and finally got a prototype.

its not perfect just yet but it only bloody works
the reason for this project was I got annoyed at the space you have to leave behind current micro mounts to allen keys, with this that's not a problem so builds can be that bit smaller
