OK, try number 4 and I think I finally got it right again! The variable was that when using the side material from the caps, accounting for the curvature. I slowly trimmed it bit by bit, testing it by pressing in the center with my tweezers, to see what it did - often it just caved in. Finally I got it just right, so when pressing on the center, it just bowed in. I also made the hole TINY. Then I trimmed 1mm off the straw. Finally, I placed it in the cart curve side-up. So, my second flavor cart is working fine -finally, I was getting tired of dripping.
All I can say is like Scotty says - patience when making these! Start slightly large and slowly trim off tiny bits and pressure test it with the tip of the tweezers or needlenose pliers, then start with a tiny hole and keep testing the flow until it's enough. Have to remember - these don't have to be quick to make, because they won't have to be replaced frequently!
I also found that, if it's getting too much liquid, pull out the cart a bit, to remove the bridge from the hole. You can still vape it when it's not pushed in all of the way. vape the liquid remaining in the atty, then push it back in to "refuel." It's almost like an auto "dip" mod!
