what we need is a PCC that has an extra spot for a 3ML juice bottle. Extra carts will help a little, but not as much as the juice bottle because most of us (well i can only speak for myself) can go through a cart in 1 session. So usually after every vape session (every 30 min) i refill the cart, and put it back in the PCC so i don't have to do it when i'm ready to vape again.
What i might do, or what would be nice, is another slot just like the one for the eRoll in that PCC. But a little wider to fit a 3ML juice bottle.
In testing, it almost fits in the current battery slot, but the bottle is too wide, so another slot that is wider would be perfect, and you can line up 2 3ML bottles which would be awesome. you would use the same cart thats in the eroll, and just keep refilling.
I wonder how much of that PCC the battery is actually taking up. i'm very surprised the crazy/genius/curious members of ECF have not cut up a PCC yet to see what is taking up space and where.
I wonder if there is enough room on the PCC to dremel out a slot like the battery slot to hold the 3ml JUICE bottle without drilling right into the battery

WHen i break this PCC, and i know i will, and probably soon. i will open the entire thing up and look.
Unless one of you guys/girld did that already and i missed the post? if so, please re post pictures of what's inside.
