iPad Air holder for K8200 frame

My K8200 is controlled by a Raspberry Pi running OctoPi, so for setting up a print, I normally use my iPad Air to control it for changing filament and so on. As I don't have a place to securely put it on the closet where the printer is standing, I already almost dropped it.

So, as a solution, I made this dock which clips to the top frame of the K8200 and can hold my iPad Air (with Smart Case) while working on the printer.
