I used this type of circuit breaker in my solar battery box. I ran into a problem where if I bump the box against something, it can break off the external button or switch. I 3D printed this shield or guard to prevent it from happening again.

Note, the edges of the guard are a bit sharp. A little filing takes care of that, but it would be a nice improvement to round them off in the 3D design. OpenSCAD source code is included.
