actively cooled case for pi4 with hifiberry dsp+dac attached

thingiverse

forced cooling pi4+hifiberry dsp+dac, uses 40mm 12v fan running at 5V (fixed connection from usb, pi) or pi pwm. el-cheapo 12v fan @5v keeps the pi cpu (no radiator) @50-52C running OSMC (kodi). The swivelling door is printed in place, gives access to pins for soldering. Uses included hifiberry mounting studs. The fan output is directed to the cpu. Designed for .6mm nozzle, but should print with .4 just fine. Supports are not needed, print in 'normal' (as used) position to make the hinge strong. I use raft, but should print without if you want to keep the bottom and flap-top table-smooth.
