Amig dehumidifier drain cap

The drain connection is a strange screw thread between 16 and 17mm. After about 10 attempts, I found the correct thread and designed this replacement drain cap. There are two pieces: the cap itself can be printed in just about anything (I used PETG). The washer should be printed in TPU or other flexible filament. The washer is a tight fit into the cap, but not too difficult. I ran the dehumidifier with the replacement drain cap for about an hour without any leak. Here is an adapter to 19mm drain hose: https://makerworld.com/en/models/728317
