Oxygen Splitter

This project is an entry for Oxygen Valve Splitter Challenge. As the requirements, material for whole components is ABS. It's using one ball valve for the regulator, on top of regulator handle it has colored points that show oxygen's flow rate. The flow rate showed by the points is not exact, red points indicating the ball valve is closed, yellow points indicating ball valve half opened and green points indicating the valve fully opened. It also use one way valve in both ports, so the oxygen flow is only one direction. Oxygen Splitter overall size : L4.5in x W2.25in x H0.625in Weight : body 21.65 gr ; Ball Valve 1.34 gr ; One Way Ball 2x0.25 gr ; One Way Sping 2x0.05 gr ; Total 23.3 gr. Port Size : dia 0.4 in
