Bed of nails 3D (origami)
Bed of nails, origami tessellation folded from a single sheet of Elephant Hide paper; no cutting or glue. It is possible to adjust the length of the spikes and/or to make them more pointed.
This design is a sequel to my Bed of Nails tessellation but now the nails come in 3D rather than flat. The molecule is still based around a 6×6 grid (36×29 for the whole model) but a bit more difficult to collapse than in the flat version. I had to resort to wet folding to make EH paper hold its shape firmly in the flat areas of the board.
