In this video 2 alternative units are used to build the same lattice as shown in the previous video. With both units I show a nice symmetrical build of 20 units I didn't show in the previous video. The first unit works really well (based on the idea EvilGnome6 wrote in his comment on the previous video), I managed to build a symmetrical version that I couldn't make with the original unit as adding the 4th set of 7 units to gain twisted tetrahedral symmetry didn't work due to too much tension. Besides that, using a single extra ring of 6, the 55 units build can be placed on a flat surface without being damaged, contrary to the big build with the original unit. The second unit doesn't work so well, already in the 27 units symmetrical version (shown in the previous video) with this unit leads to some bad connections, the unit is too rigid.
