When I got my x7, the original case has some issues. The face kept coming off (it's just glued on, and not very well). I used Fusion360 to design a new case for the remote board. I figured instead of having the face snap/glue on, I would attach it with screws. This will make sure it doesn't come off. I reused the magnets from the original case (use caution when removing them). They are pressed into the new case after heating it with a heat gun.
