Above we see a roughly sketched out tentacle arm with three solenoids per segment and five segments. The value of l is the length of each solenoid, which varies linearly. The height of each solenoid is given by z, which is an integration of l plus added thickness for the base. The printer is capable of printing flex, magnetic iron, and carbon Fiber PLA among other materials, so we can make all the single-material parts we need for this design.
