I came up with this idea using Kydex for a frame sheet. It was about $10 in materials and took me about 20 minutes to make. I used .80 Kydex and two aluminum 3/16 screw posts. It weighs in at about 3oz. It is a clam shell design so there are no attachment points to the frame itself and stays firmly in place because it is molded to the frame. I hope the attached photos turn out (I haven’t figured out how to post full pictures yet). I will post an update when I get a chance to test it out further.
