Illustration of the origami method of an excavator. Use only a piece of paper to fold a decent mini version. Come and try it~ red dotted line = valley fold, red dotted line = peak fold, black dotted line = Invisible polyline. In view of the poor use of PS, there may be several lines that do not meet the above definition, please forgive me╮(╯▽╰)╭
There is a peak that I forgot to mark →▽→ Let’s experience it for ourselves.
Back and forth means folding in and out again.
Turn on flattening.
