Kindle Oasis Holder

I love my Kindle Oasis but I have problems holding it comfortably without triggering the screen, the screen can be deactivated but you then lose functionality. this handle is my crude way of improving the situation - making the the Kindle easier to hold without activating the screen inadvertently. I am sure it can be improved and certainly made to look better! but it works for me.
It was printed on an Ultimaker 2+ extended with standard quick settings.
