NOTE: This is a 3D Model, not a physical print*
Explore the fantastic world of metamaterials! Structures with a negative Poisson's Ratio that are able to stretch AND become thicker perpendicular to the applied force. It's a combination of physics and origami, transformed and adapted into a 3D printed version that allows motion and shapeshifts with a simple stretch.
All three structures are very precise, with walls and cuts that are 0.5mm. Use a 0.4mm Nozzle (The one that most desktop 3D printers use) and make sure your bed is properly leveled, otherwise the walls are going stick together.
Use a 0.2mm height so you get 4 layers, for a total of a 1.2mm structure. You can play around with the sizes to create bigger and more solid structures.
In terms of materials, I recommend 95A TPU to make it strong and reliable, if your filament is too soft the structure could be ripped off.
