Fall Resistive Metamaterial Concept - Part 2

A concept i have been working on, a metamaterial that i hope will slow down a fall, by creating flow compression within a repeated, functional (nano) 3D printable shape, as a material. i tried to use negative space to maximize the effect from the available space per iteration. one could try and imagine how the flow would work in this system to slow down a fall. the idea is to use duality, to make one path quick, fast, easy, and thus preferable naturally, and one path long, slow and hard naturally to guide the flow through the shape as intended. it is a untested concept i am planning on testing some day to see if intelligently designed shape can actually makes a difference in falling velocity, as i suspect it does, even in a large enough vacuum.
