This is a very compact housing for the HQ camera board and a Raspberry 3 A+ board.
There is smace left to place a steel washer within the printed wall of the housing. I use it to mount a ZoomH1 audio recorder with a magnetic holder on top of the housing.
cut out the 0.4mm thin wall for the tripod mount of the camera HQ-board after printing.
