B) Countersink holes
Countersink holes for 2-56 flat head screws. The metal is too thin for full depth countersink. Just stop when you start to enlarge the clearance hole out the other side. The thicker Prism Box Lid will accept a full depth countersink. The remaining depth is tapped 2-56 so you can screw in a flat-headed screw pointing out ofn the box and the screw head will not rise above the inside surface of the box and scratch the glass prisms.
