Life got hectic... I have the parts printed for what should be the beta test article, but need the time to post process and assemble.So, how's it coming?
It is that o-ring... And it's already a thicker cross section and lower duro (to better conform to to surface imperfections). The outer barrel interior mouthpiece opening is radiused to help prevent catching and pinching the o-ring. I am, however, still working on mapping an oval (rather than square) o-ring groove onto the inner barrel... it's a limitation of my skill with the modelling software more than anything.Nice!
So the 1 bubble / second leak is this o-ring?

Maybe a thicker cross section o-ring? You have it as a square, what about more of an oval shape for the o-ring to seat in? Or maybe a slightly radius slot making the corners less abrupt to seat the o-ring in....
Just my $0.02, and hardly worth anything these days with inflation....
