Printable Oxygen Splitter

This is my take on an easily printable oxygen "Y" with dual control. The main piece is modeled in such a way that the previous layer will always support the following layer (learned from other prints). The design is simple, yet will function as the design criteria states it must. The build plate would consist of three separate components (2) of the dials and (1) main component or "Y". Instead of creating nipples that slide into the hosing I went for a cavity that would receive the hosing to maintain "printablilty" (assuming the nipples would need support material). The countersunk holes are for a standard drywall screw but would also work as a through hole for a zip tie if needed to centralize and secure the control (say between two beds close to the supply tank). This device was designed for standard medical grade tubing (8mm O.D. with 5mm I.D.). The tube receptacles have a 1° draft to them to ensure a snug fit and the exterior clamps (to hold tube in place) are .25mm "tight" of the tubing O.D. Hope You Like It!
