Oxygen to 9/16" screw adapter

You can print this model on most printers without support. It is there to help connecting different oxygen-connectors in healthcare use cases. 

However, it is important to say that it isn't an medical certified device, and I highly recommend buying an certified device if the oxygen system should work in critical care or else, in terms of the strength of the material. 

I printed the Model with PLA and it works just fine, but maybe ABS or PET works better in terms of strength.
