This is an addition to the cool machine already uploaded. It is made of ball and socket joints and locked together with 1/8" round elastic, epoxied in the tip and tied around a bar in the base piece after drawing tension enough to hold the tentacle horizontal without drooping. It helps to lightly sand the ball joint, to provide more friction. it was made at 100% scale and can be reduced but no more than 20%. I suggest using hot glue to attach to the machine head so you can take it out if the elastic stretches or breaks.Designed with TinkerCad and printed on a Prusa I3.
