I created a better servo guard, all be it is slightly heavier then Flite Tests Mini Zero servo guard, but it will last a lot longer then their simple foam board version. Simply print the guards vertical with supports.

Position on to the bottom of the wings as you feel fit, I positioned mine so it would protect the servo arm (There is a left and a right guard so make the proper sides of the wings) Once you know the placement of the guards add some glue to them and push the spikes into the wing to secure them in place.
