I tried a few modes, but finally found the one, that works for me, by myself.
Why Blue heart? Cause after few refills the foam looks like one.
No need in special tools. Very simple, and supply very good juice flow, no leaks. Here is the pictures:
Just cut a triangle shape.
Something like this
Put about 12 drops of juice (leave about 2mm), and then insert the foam as shown on picture.
And press with paper clip right in the middle. this will create space in the middle and sides will lock the foam inside. You may add couple more drops on top of the foam.
This is it.
UPD: forgot to say - plenty room for juice (don't have to refill for 3-4 hours). dry cart completely without burn taste.
