Base flange; an edge flange at 90 deg; four made together, the corners closed on the mitre plane
with the rule's gap, at 90, 72 (leaning out, the ends run on along a slant) and 108 deg (leaning
in, cut back); round, rectangular and tear reliefs; a hem; a fold, unfolded and refolded; the
tray's flat pattern (outline size and area, bend lines); a bracket with a hole and a flange on a
flange. K = 0.5, so every volume is T x the flat area. The 108 deg tray is a sheet-metal rig case too.
