THE METHOD / 01
A clear wayfrom start to finish.
Flat width = base width + twice the side height. Dashed lines fold; solid lines cut. Corner tabs attach to the inside of adjacent sides.
Keep the assumptions clear
Dimensions describe fold lines. Card thickness and cutting tolerances are not modeled; make a scrap-paper test first.
