@Rodbotic

Great Job on the paper! I'll try to print it when I get home.

@Rohan_247

Did this thing work as expected?

@Rodbotic

Replying to @Rohan_247 :

Yes it did! I printed the 3 String version. I used a pair of sticks like a marionette, so I could pull the string independently.

@Rohan_247

Replying to @Rodbotic :

That's amazing 😍 Now we just have to copy paste the structure and just include few robotic stuff to make it move independently

.4mm P1S tpu95, works great thanks! fishing line for articulation, hot glue for grippers

@rad_rat

hey could you post a mount type thing for this it looks like there is supposed to be one with the extrusion at the back but I don’t see a model yet and wondered if you could post one that I can counter weigh and use the tentacle with my hands?

@rad_rat

are you making the 3 string one for 3d grabbing?

okay cool got it thank you very much.

@rad_rat

that's wild this research just came out

@002ik

guys can u expain how to do this? im new to 3d printing

@MechatronicsAS

Is there anyone that has gotten to print this on a Creality Ender 3 v3 KE? TPU is aggravating.

@DeansElectronic

I printed the 3 string version on a v3 SE. I used the generic TPU settings from Orca Slicer and filament straight out of a dryer, but it was still super stringy.

@rad_rat

very interesting

@user_2304889044

Could you send a video of the arm in action
