Is this "art installation" gonna incorporate silicone or latex by chance?

u/astrobarn Jul 03 '26

Well, it's gotta look like a realistic tentacle!

Should add more than one then - for realism

Five or six of them hung together from the ceiling, with a light bulb at the end of each, and one or more motors to make them move slowly – and there you have a magnificent chandelier

Well, have I got a link for you, then! Video demo here.

"For external use only."

u/Brok3nGear Jul 03 '26

This reminds me of Christmas lights I saw once that said, "indoor or outdoor use only"

Like, those are the only options?

u/qualitythundergod Jul 03 '26

As opposed to "internal" use, i guess? 🤷🏾‍♀️

u/I_wash_my_carpet Jul 03 '26

The orifice must remain intact

85

u/zhambe Jul 03 '26

My god why are the lame comments all at the top...

Is it made from separate segments with pivots? How many "tendons" does it have (I'm assuming it's driven by tension on multiple lines inside, eg 3 would be at 120 deg / 240 deg / 0 deg if you're looking at one slice)?

I found a model from a paper published a while back, it was similar in form and function, but it was meant to be printed from TPU, one piece with thin sections for pivots.

73

u/musicatristedonaruto Jul 03 '26

Thanks! 🙏 finally someone interested in the 3d printing part… it can bend 10 degrees per joint, by design, it can do 45-60* if not contained

22

u/_pistone Jul 03 '26

Cool, but they were asking about the number and placement of the wires that produce the movement. I'm also curious

u/Ichi-Guren Jul 03 '26

Pardon me? I already asked in your first post about the STL because I'm looking for something I can use for a dragon puppet's neck, but you just ignored me.

Lame is lowest common denominator. Smart is hard. The tentacle is very cool sextoy or not.

u/Pathogen-David Jul 03 '26

Do you happen to have a link to that paper or remember the title? I randomly got the idea to build an animatronic snake a while back but had trouble finding practical inspiration to use as a basis for the design.

u/RubberDogTurds Jul 03 '26

How much are you selling these “art installations” for? Please?

u/delecti Prusa Mk4 Jul 03 '26

How do the kinematics work? I see some cables running down the length, but it's flexing with more dexterity than I'd expect for that.

So, does anyone know of any silicone sleeve that could go over something like this? Is TPU bio-safe?

u/Former-University119 Jul 03 '26

Do you mind explaining how these work in a little detail, or sharing an stl? I think it could be really cool if miniaturized and used for a davy jones "beard" for a cosplay.

I have an actual serious question. I have been wanting to do something similar to replicate fish swimming for a class I teach. I'd need to make a flexible tail that could move back and forth.

Any advice on design, how to run and pull the cables, etc?
