Today I had an even better idea. Instead of making a new lower plastic I desided that it would be better to make an adaptor for Ody's base so Iatty will fit there. The advantage is that we will not be forced to change Iatty's lower plastic every time we want to put it inside Ody lol
Ody works with GG adapters if you notice. Its the best idea ever as I see it. You put a GG adapter inside base and you have different configurations like CE2 tank, atomizers, cartos etc. Something like this we can do for Iatty, so Iatty internal pieces will fit on Ody!
