Simple 2d extruded lattice using octagons - both simple and offset overlay creating a denser more intricate pattern - though the edges will need a frame in practice

Simple script if not the most efficient way of doing this.

octtile(width of line between octagons, length of one side of an octagon, no of octagons on the xaxis, no of octagons on the y axis).

First octagon is centered on the origin.

denseoctile uses the same process to create an offset overlay creating a more intricate stronger lattice.

Intended for light open boxes and planar systems
