4 chest armor options for your Kerfur Dummy! Variant B is the one I'm most happy with, I think it looks the best in person while also not compromising the articulation of the D13.
Remixed off the Type F chest, so you'll need to use their inner armor and also the female chest body frame.

The author remixed this model.
Used the Type F basic chest as the base to work off of.
