Summary

EDIT: Now with quick-filler http://www.thingiverse.com/thing:1925009

New rules here state an max of 2ml tank for ecigarettes. This one is 12ml :D

Printed in PETG at max possible heat. It is important to get good layer bonding

Included version without the XXL and VAPE ON text

Version 1 leaked slightly after a whole night on its side.
This is version 2 with an ekstra ledge inside to keep it sealed this might be enough to keep it from leaking on its own. If not then add a washer like in the pic, just file down the top in about the same thickness as the washer to get an good fit again.

Please note DON`T tighten by turning the tank, you will tighten it to much and wont be able to get the buttom of the clearomizer of. If this happens use this: http://www.thingiverse.com/thing:1442741
It works really well at getting of stuck clearomizers, print in PETG so it has some flex to it or file down the edges in the middle.
