Hello All I made this Diffusor for Shisha Tubes because I thought it should be flexible. All diameters will adapt to the shisha tube outer diameter. It was made to stick over the shisha tube. It is colored green for better visuability. The Diffusor wall should be thicker than the holding ring wall to stop It it goed to strong on the tube the 0.8mm wall should get easy on the tube when you heat the tube a little up. Have Fun ! ;-)

Try V2 ;-)
