IR Board - how to protect

[Cts519]

Since it is an exposed PCB, my plan was to use kapton tape for heat and a printed part as a bumper For crashes.

Any suggestions? Photos?

Thanks!

I have kapton tape, about 5 layers, on the back of it. I also wrapped my heat block with the tape. It would take a lot to hit it, so no protection there.
