F3P circular check valve [Rev1]

thingiverse

<h1>F3P Circular Check Valve</h1> This is a fully 3D printed check valve. Designed to be usable with the humman breath due to is low cracking pressure. Also the cracking pressure can be adjusting by tweaking the thickness of the membrane/diaphragme. I think it can help many people to build their on project on the top of this. I have seen few project actually not terminated cause they was looking for a suitable and decent check valve. I take advantage of the smooth printed side of body and diaphragme to get the seal. I recommand to use glue to seal body and nozzle. The diaphragme will be stucked by the between two pieces, body and nozzle. Membrane should be the more precise part.
