I lost the adapter to connect the air hose to my mobile air conditioner.
My model name is ‘CM 30952 we’.
It seems there are similar models where this adapter might fit, too.

Made the adapter for a 100mm hose. If requested I can add other diameters.

UPDATE: repaired most of the source files to make the hose size variable. Version 2 works the same like the first upload.

To make the print easier the small hook for the long hole is a separate object. After printing the hook and the adapter you can glue or weld it in place with a 3d print pen.

Please print it at least with PETG or another material which can withstand heat. On hot days the adapter and the hose can get quite warm.

The provided 3mf file has all models ready to print. The part where the hose get's mounted has a fuzzy skin modifier for a better grip. The file also contains a wall adapter. It might be usable for you. The bigger part should be printed in PETG (or better), the seal can also be printed in PETG or a flexible material which is heatproof.
