Raspberry case with fan

thingiverse

RASPBERRY CASE WITH 50mm FAN for active cooling (for RPI3 and RPI4) A DCDC supply can be added to reduce the 5V from RPI header to a lower value for fan noise reduction Hardware needed : - 4 columns M3x15mm (int/int thread or int/ext thread) - 3 M3 screws (>=8mm) on the fan_holder plate - 2 M3 screws for fan installation (adapt length to fan thickness) - 4 M3 screws (>=8mm) on bottom plate (not need if used int/ext thread column) NB: the RPI holes (2.7mm) are too small and must be (carefully!) drilled at 3mm to adapt to the M3 screws Foam pads can be added on bottom plate to limit also the vibrations (mandatory to compensate bottom screws thickness if used int/int thread columns)
