O2 Regulator

A straightforward three piece FDM printed O2 splitter. Both channels are independantly throttled by the respective knobs which compress the oxygen tubes and thus regulates the flow. A spring detente indexes the knobs, positively locking them to ensure they do not unwind under pressure. An end stop also ensures the user does not wind the knob past it's maximum/minimum setting. This was designed to allow printing without the need for suppports or rafts.
