Portable Air Conditioner duct adapter

thingiverse

This is an adapter for my portable air conditioner. The supplied duct was not long enough to reach from my basement floor to the window. I measured the existing duct round plastic piece that clips into place and recreated a similar circle in Tinkercad. The goal was to fit a 5 inch duct to the hole that was for the 6 inch supplied duct. The final piece is 154.7mm of diameter and 13.15mm of height. Printed in under 3 hours using 35g of material. See pictures for final fit. The first picture shows the adapter clipped in place on the unit. The third picture presents the acrylic insert with extending tabs I made for my casement window since the air conditioner only came with plastic inserts for sliding windows. The last picture shows how I attached the extender duct to the original duct.
