KOENIC AC Hose Adapter for Tilt Windows

🚨Note: If you are looking for a solution for a wall pass-through or roller shutter, also check out my AC hose flange: KOENIC AC Hose Flange

This model is a remix of the AC vent adapter for tilt windows by Synergyx26.
The original model is, according to him, from Printables: Air conditioner exhaust into the ventilation window

My remix was adapted for the exhaust hose of the mobile air conditioner KOENIC KAC 12022.
The adapter may also fit other models or manufacturers

Changes compared to the original

• Integration of the bayonet lock of the exhaust hose (see images 6 & 7)
• Enlargement of the exhaust outlet (see image 8) for better airflow

The adapter can be used seamlessly with the original hose system of the KOENIC air conditioner and conveniently hung in a tilted window. It is more efficient to additionally install a window seal (for example KOENIC KWS 122)

Thank you for your comments and feedback!😻

Since some of you need different dimensions for the exhaust outlet, I have added custom parameters to the model. This allows you to easily adjust the size and shape of the exhaust outlet to your requirements
