The braid is constructed by weaving wire over a 3D-printed template. The template is designed to make actuators that have a 20 degree winding angle when surrounding a tube with a 3/8" outer diameter. The template is designed so that the braid length can be varied in multiples of 10 cm (10 cm, 20 cm, 30 cm etc.). The actuator we present here is designed to work with a 30 cm braid.
