The Roll_Cage prints better upside down( dead bug style ) and I used OpenSCAD to do the positioning:

module rotateCamMount () {
translate([10,0,83.0])
rotate([0,8,0])
rotate([-90,0,0]) import("Magnet_Roll_Cage_v2.stl");
}

The Plate needs re-positioning too:

module rotatePlate () {
translate([25,0,0.0]) // -75 works get just the camera mount above 0,0
rotate([0,0,0]) //-2.9,0,0 is close
rotate([90,0,0]) import("Magnet_Plate_v7.stl");
}

But it also needs the clip slots deepened and widened since a few members of the club had problem and had to grind the plate width at the pins. I deepened the slots from 1.5mm to 2.0mm deep.

module rPiPlate() {
difference() {
rotatePlate();
addPlatePinClearance();
}
}
module addPlatePinClearance() {
platePinH=3.0;
plateH=5.0;
pinSlotW=10;
pinSlotL=25;
//end 1
translate([90,-12.5,plateH-(plateH-platePinH)/2]) cube([pinSlotL,pinSlotW,plateH-platePinH],center=true);
translate([90,12.5,plateH-(plateH-platePinH)/2]) cube([pinSlotL,pinSlotW,plateH-platePinH],center=true);
//end 2
translate([-85,-12.5,plateH-(plateH-platePinH)/2]) cube([pinSlotL,pinSlotW,plateH-platePinH],center=true);
translate([-85,12.5,plateH-(plateH-platePinH)/2]) cube([pinSlotL,pinSlotW,plateH-platePinH],center=true);
}
