@ragnorokk maybe permanently wasn't the best choice of words, though the bigger ss piece will indeed be inserted with the idea of it never coming out again. I have made a custom drill bit that will take a little more force to install and remove the ss. The smaller 1/4" ss is held in place by an o-ring and also now has a custom tapir bit that will prevent it from pushing inside the hole. The beta units have the o-ring but not the tapir hole.
As @WakeAndVape said, you could use it inverted as long as you sandwich everything with a screen. We will have a direct wpa by late summer/fall.
