Chern made this (1,0) P-type triply periodic minimal surface with 4mm beads many years ago. I might have posted it long time ago, but forgot to make a suitable keywords for that post, so I couldn't find anywhere in this blog.
Chern used a different color coding for this bead model, i.e. orange for hexagons and black and organe alternatively for octagons. Since there is no bead which is not in octagons, one would get a single color bead model by using the color coding we adopted typically.
