I changed the principle of the lock to close the lid on the valve base - I made my models with a bayonet-type lock. Such a lock makes it easy to open the lid and change the filter. The valve membrane 0.3 mm thick (Z0.2 initial layer and Z0.1 layer height, total 2 layers) was printed from flexible plastic Monofilament Elastan D-100 (Ukraine).
