I just printed a small Case, to carry my Nano QX fpv in my Backpack. I really like how the shape turned out ! The Top is hold by friction fit tabs, holds it together very strong. On the Picture you see the prototype design, which was 3 piece (two halves and bar, glued in) as the box is bigger than my print size ;( On Request, I've also uploaded the 3 Piece Design, for smaller Printers, Marked as [3 Piece Design]
