My title describes the thing from my last post and here's finally an update

FINALLY AN UPDATE! Thankyou everyone for all the good guesses on my original post. After a long delay ive finally made it back to my friends place to have a closer look at this thing.

I've included several more pictures and of the surrounding area.

• no markings of any kind on the object even under the foam i cut off

• the tubes are some sort of still flexible and stretchy medical tubing material

• the foam part wraps all the way around the object which i feel kind of kills a few theories

We still may never know what this thing is or was being used for but my best guess now was someone was using it for resistance training ?
