I've just released a novel way of mounting your Pimoroni Camera Holder/Stand on the Pibow case, the kit comes with a piece of 3mm perspex, 1/4" nut & bolt (tripod mount size) and a replacement m3 screw for the Pibow case.
It allows you to mount your Pimoroni Camera Holder/Stand in any corner on the top of the Pibow case and keep it there safely.
I know it's a simple idea, but I've not seen anything similar so far
