modified Disc-connectors.. use as Tentacle or Tail

my parts have tree slits instead of two.
joint lenght is constant.
For internal animatronic bowden system.

Feel free to help me making this a customizable piece, because i cant do openscad.

I added a plate but i think its best not to print them all at once.
should be scalable a bit.. but not tested yet.

Print plate twice and assemble in double lenght...

put some elastic sock over finished piece and multicoat that with silicone.. or maybe this could be used:
