If printing this case for a Pi 5 with the active cooler fan/heatsink, a slight modification is required. On the Pi 5 with the active cooler. the 'lower' snap-in for the heatsink blocks the catch on the top part of the case and will not allow it to close. I modified the design slightly to make a notch for the heatsink snap-in to fit through. After this slight mod, works great. Thanks for a good design.
