My grandma has a 1ft adapter hose that would attach Medline supersoft adult nasal cannula (part # HCSU4514S) to a regular oxygen hose. Instead of using the regular press fit plastic adapters (which still work for this hose btw if you get the extender one) it uses a threaded 14mm connector.
Long story short, her 1 ft adapter hose that joined to standard hose got old and there were none left. I decided to model this. It printed out great and fits like a glove.
Id recommend printing at greater than 50% infill, maybe even 100% so that the pores of the plastic dont leak oxygen.
Any connectors that are threaded like this will leak some air (poor manufacturer design imo) its best to use the tube extender plastic piece and just shove it in for a air tight seal, but this works as well if you dont use high o2 levels.
