About this 3D model

Presented here on a 40mm base, the lightning arcs are roughly 3.5" long and angled at 60°. Thus if you wanted to, you could arrange 3 of them in a 7"x7"x7" sided triangle. If you do this, don't forget to mirror one, so the heights of the zapps lines up correctly. The little armour panel on the top can be replaced by a decorative squid, or left off.
