Koenic Air Con Extractor 90

I needed an adapter for my basement Koenic air conditioner, since the room gets pretty warm when I’m running my two printers in my small home lab. I couldn’t find any ready-made solution, so I designed one myself in Blender.This model adapts the Koenic AC outlet to a standard flexible exhaust hose.The window-vent connector plate measures 125 × 125 mm, with the four mounting screw holes spaced 110 × 110 mm.The lower end is sized to fit a standard AC exhaust hose like the one shown in the photos.For reference, my print took about 5.5 + 7.5 hours depending on orientation and support configuration . Your time may vary based on layer height, speed, and material.I recommend printing this in PETG for better heat resistance and durability, especially if your AC or exhaust hose gets warm during use. PLA works, but may deform in hotter environments.It’s a simple, functional part, and I hope it’s useful for anyone who needs the same kind of adapter.If you print it, feel free to share feedback or
