Simple 3D Printable Flow Control Valve

grabcad

Simple flow control valve that can be easily manufactured using 3D printing technology. Designed as part of the OpenRespirator.org initiative. If you create this, please share your experience with the tolerance settings. It worked well on my printer but the tolerances were intended to be precise to prevent leakage. A secondary version with looser tolerances is available for anyone experiencing difficulties with the fit. Also note that there are two M8 threaded ports with plugs included. These features were added by request to allow for different configuration options (bleed port, mixing port, etc.). There is also another version of the valve that includes a built-in meter marker to help visually determine how open or closed the valve is.
