In this design, the membrane is actually 3D printable, either out of "_normal_" material (_preferably PETG_) or out of flexible filament. While this requieres a larger diameter to obtain the low cracking pressure, this allows the valve to automatically close without negatiev pressure, which is needed for breathing-related application as we aren't constantly breathing in an out, and there can be a second of hang durng which a softer membrane wouldn't close and would let air go the wrong way.
