Okay, so here is the updated plastic version that I'm currently using. If you're not familiar with the progress of this mod, check the very first posting.
What I'm currently using is plastic strips. You can use almost any flat thin plastic. A 2 liter bottle would work as long as it's thin, but you'll want to cut vertical strips. I used the plastic container that some Christmas cookies came in. A free lifetime supply! Now that's turning trash into treasure.
The only downside is that when you refill you might need to center the strip in the middle. Remember, the strip does
NOT provide support. It is really only there to keep the filler/plug from slipping down into the bottom of the cart. If it's centered, juice naturally flows on either side. Even if it slides to one side juice still flows. I think this outperforms the "wedge" version, due to better juice flow and less surface area for the juice to adhere, but be aware of both of them as one might work better for you if you're not using a 510 cart with a lip on it. The wedge worked great on the 801 but I hated the 801 carts. The air chambers went right to the bottom so I was sucking up a lot of juice. My 801 is not a 100% dripping only model, but that's okay, too.
Here's a diagram of the strips I am currently using:
And here is the mod in action. I really should have used a different colored plastic so it would show up better. And you can't tell, but the finished cart is as close to perfection as you can come...
If you are using the vent filters, top off the cart for your first few vapes. It causes the filler to become a solid piece. After than you're good to go.
I loved the ADM, with it's ingenious spring, but I love this better. I can top off the cart on the go. I can fill it up. But more importantly, it gives all the benefits of the original ADM, but without the metallic aftertaste. The deeper filler creates a better seal and I have never had a flooding issue. And it holds the same number of drops as the original ADM (approximately 12).
I've just started using KR8 cartomizers and I have to admit, this mod is easier to fill and provides better flavor and vapor. I like having the KR8 cartomizers to play with and as a back up, but this mod will make a believer out of anyone. Yes, that includes 501 direct drippers!
