Please don't change the 3ml. The only mod I have done to mine is to thin up the top seal as lord Davon showed us how to do. That was just so I can fit my own drip tip on it. If you don't do that - the tank cover won't go down and snap into position. I have to say - this tank and my new drip tip on my Provari is the Hawtness . I will take a photo in a minute and show you!
