Improved Oxygen Restrictor

grabcad

This revised design boasts a separate splitter and two regulators, built with printability, ease of use, reliability, and economy in mind. Improvements from the previous version comprise an enhanced restrictor, achieved by optimizing the gap through which the oxygen line feeds; less material usage for quicker prints and better economy; simplified operation as the restrictor is moved nearer to the patient; and a larger flow volume. The filament requirement stands at 1.1 meters of 1.75 mm filament, with a print time of 20 minutes, while measurements are 60x15x12mm.
