I bought a diffused down stem that is 2.5 inches past the frost. It fits in my bong but is just millimeters too long because it hits the base. I was looking for ideas to shorten it. I could sand it down but I would lose the small hole in the bottom and none of the smoke would go through the slits in the side. I have also thought if I could get the joint to sit a bit higher but I don't know what I could do for that. Any advice?
i have seen joint exterds before or they were somthing like that maybe look into that or maybe a Grommet of some sort
