Print one of everything, except print 2 of the center clamps and 2 sub rings.

The left and right side of the case are held together like the original, with 2 M5x40 screws and 2 M5 nuts. One 5mm hole needs to be drilled into the handle for the center clamp. Hold one side of the clamp in position between the minirigs and drill in the center of the hole, all the way through the handle. An M5 nut secures both sides of the center clamp together. (see last 2 pictures)

Printed in PETG at 0.2mm with 50% infill. The only part that requires supports is the center clamp.
