Portable Air Conditioner duct adapter

thingiverse

This is an extension for my portable air conditioner. The provided hose was too short to reach from my basement floor to the window. I measured the existing round plastic piece that clips into place and created a matching circle in Tinkercad. The objective was to fit a 5 inch hose to the hole designed for the 6 inch supplied hose. The final piece measures 154.7mm of diameter and 13.15mm of thickness. Fabricated in under 3 hours using 35g of material. View photos for final fitment. The first photo displays the adapter securely clipped into place on the unit. The third photo features the acrylic insert with extending tabs I designed for my casement window since the air conditioner only came with plastic inserts for sliding windows. The last photo demonstrates how I attached the extension hose to the original hose.
