Printed it on the flat side (with the holes), with supports for the lip part.
Used pretty default settings for PLA, brims on all sides for the main part, and 100% infill for the ball joints (4x). Said balls can be press fitted in the holes.
Most will have to split the part, in which case I suggest splitting at half height and use connectors, then glue (or not, it'll be held together by the case's back panel once snapped in).
One the balls and frame are assembled, it should snap in the case, and the back panel in the spacer frame.
Don't hesitate if you have any questions ! :)
