Here are some replacement parts that fit with the following popular Atomizers and Bases.
Also added the screw sizes for each RTA cause the provided onboard screws are mostly bad and
have to be exchanged with A2 or A4 stainless steel screws.
Cause of the different screw headsizes for bottom fill holes I decided to exchange them with
headless screws.
7-in-1 Hex Stainless Steel Hex Key Wrenches Set SKU 1404201 - perfect tools for listed headless screws

Attention! The GT-T V2 has a special designed chimney so at the moment only bell caps will really work! Hoping that FT will offer some extra chimneys to make it compatible to the listed tank sections
