Was thumbing through a NatGeo magazine and saw the origami picture and immediately thought of 3D-printed cone baffles.

Then read the article about otters and maybe a 3D-printed version of otter hair instead of felt.

Last but not least, honeycomb hex shapes to trap air.

Too much time on my hands, I guess.
