Made this as a direct copy of the OEM Ford Oil Cap vent tube. After 40 years of use the plastic became brittle and broke during an oil change. Had a hard time sourcing another vent tube to connect to the hose and vent cap. Decided to try my luck at printing the part with PETG and seeing how long it can survive in the harsh environment of an engine bay. So far so good.
