I have an Ego twist and recently purchased a few tanks, the trouble is they don't seem to sit flush. I realize its only aesthetics but i was wondering where I could find a decent "skirt" to fit an Artemas slim 2.0 ml tank dct or vivi nova 2.5ml tank. Every place i have found online seems to have adapters to fit ego products on a 510 batt but nothing where the male end of the 510 item could fit flush into an Ego batt.
