I know that a lot of the 510 cartomizers have a plastic tip that once you remove it cannot be put back in (because it was glued in to start with)
So here's my find...
If you trim off a cartridge casing from a DSE901 right at the point where it gets larger (to press-fit it into the 901 carts), it will fit into the now open end of the cartomizer giving you a "whistle tip"
you need to trim it short, though because it is long enough to poke into the cartomizer filling if you don't cut it off. I used a pocket knife to trim mine. the plastic isn't really thick at that point, so it cuts off pretty easily.
It removes easily to refill your cartomizer as well.
