I got an old air pump that works and the air lines are fine. Hated thinking I had to replace the whole connector for just a rubber boot. Of course I made a quick print to replace the rubber seal that rots in the connector housing.
Note: I have used it about 4 times over the past 2 months. So I am not sure about the longevity.
This took me about 7 minutes to print using TPU.
