I don't have many good images of it so forgive the shitty cropping but the way I've devised to wear it is with two long strips sewn into the back (you can kinda see in the other pic) that have snap fasteners connecting to another pair on the straps of my plate carrier. The bottom of the piece sits on the lip of my plate, three velcro patches keep it from wiggling, and the two straps hold the weight up.

It doesn't touch me and the inside of the plate has a curve, so even if I look straight down, there's no intersection. Weight is also a non-issue on account of it being an accessory to the PC.

HOWEVER, it does wiggle. I kinda half assed the attachment points and doing jumping jacks will dislodge the velcro. It hitting me in motion isn't an issue, since the concave surface means it'll be stopped my collarbone before my neck, but it does nonetheless wiggle.
