for the pi that would allow me to remove it without screws. this is what i have come up with so far - it is a mash up of a quick release mount i made and this case. i like that case because it is a nice clean design, and most importantly it is a simple rectangular shape. i'm working the bugs out now, but my first print of the base part seems to work just fine. it uses a spring from a cheap pen and just slides and snaps together. the orange part is a button that releases the case from the mount and the case can go in
