VAMP pneumatic muscle

VAMP - Vacuum-actuated muscle-inspired pneumatic structures
This is the CAD I modelled from the diagrams in the paper

silicone.stl is not for printing, it is just there to show the shape of the final cast
mold_walls and mold_base are printed normally
mold_top is a 36 x 49 x 3mm acrylic plate, but you can try printing it if you don't have the material

The two silicone halves are cast from the mold and joined together by uncured silicone

Fusion 360 file included. I did not know how to use the "pattern" feature when I created it. It could probably be made easier with it.
