Air Conditioning Unit Exhaust adapter 150mm pipe

I needed a 2nd exhaust adapter for a 2nd hose. This is a copy of the original, drawn by me. It is suitable for a 150mm diameter hose. I've attached the Fusion 360 file in case anyone wants to adjust the size to suit their unit. The version I printed needed supports but the version uploaded does not. I printed in PETG (as it was loaded in the printer!)
