This is my next mobile stand iteration which may hold almost every mobile device from the smallest iPhone till the 10.5" iPad.
Features:
I have uploaded an extra version with a dedicated holder for the 1st generation Apple Pencil as well as a bigger version which holds the biggest, 12.9" iPad properly even in portrait mode.
