It would be quite easy to make and would make my life easier with the 6 tanks i have setup for different flavors. A spring loaded ring on it that you pull down to release the tank and to put another one on. You all have probably seen the bigger version on hoses and such I forget the exact name of them atm. I change flavors constantly and would be the first to order one. The locking piece would screw into the battery and the other into the tank, so sell the in pack with atleast one base and 3 or 4 tank attachments please XD
