This is just a simple demonstration of the benefits of 3d printing on damaged devices. Often very small damages makes devices completely useless, just like the broken bracket of my headlamp. Just a part of minimal size was broken out, but the lamp could not be used anymore. With ridiculously small effort this could be fixed by a 3d-printed replacement that was glued to the bracket. Less than 1 gram of PLA was needed to save a lot of money :-)
