Parametric Y Connector

thingiverse

A doctor friend recently mentioned a possible shortage of Y junctions for ventilator hoses, especially in cases where multiple patients need to be serviced off a single machine, like the setup shown here: https://hackaday.com/2020/03/19/saving-4-patients-with-just-1-ventilator/. I created a parametric OpenSCAD file that can accommodate most reasonable tubing dimensions. To avoid support structures, I recommend keeping the branch angle under 90 degrees. The scad file adjusts the branch length according to the split angle to ensure clearance for the lip. Safety considerations include: - Use at your own risk; neither liable nor responsible. - 3D printed items can be porous and permeable. - Check the SDS of any print for particulates and hazardous volatile compounds. - This solution will be inferior to similar parts from approved sources. - When moving the part from the print bed to a sealed container, assume you have COVID-19.
