Thanx a lot!
I just found 165mm black heavy duty heat shrink tube, same thing we use for wires only big in size. OMG, I was lookin for it in largest electric stuff shops in my capital city, but largest shrink tube was 75mm.
But I found it , we call it: "black market ". It is market in criminal side of city there you can buy everithing- old stuff, new stuff, many things that was stollen, for an example, car mirrors, bicycles, tools, tv’s…
Yeah! I can’t understund how that market can be working, but I found my stuff there
I bought 1meter of 165mm heat shrink tube for 10 EUR.
