Laser Cut Adjustable Mount for Mirror and Laser

thingiverse

I've made this to bounce laser on mirror to create a security field ;) You will need M3 scew and bolt (I used 16mm length), and spring. You can look at the side diagram to see where the spring goes. The idea, is by adjusting the M3 screw length, the mirror angle will change just a little, allowing to very precise laser bounce.
