Portable Air Con duct adapter

thingiverse

In our older house, we have no AC upstairs. So to help the kids sleep we bought a portable AC. The unit uses a push in duct pipe to exhaust the hot air. This is pressurised to a degree thanks to the fans, and it leaked and would fall out with ease. I created this adapter to insert and lock into the back of AC unit, with the duct piping going over the top of the outlet and secured with duct tape. It now provides a leak free join from the AC to the exhaust set up. This was made for a Dimplex unit with a 150mm diameter outlet, with 4 tabs, top/bottom/both sides. May work on other machines with the same style and size. Wife wanted me to sell it, however, I'd prefer to offer the design for free to anyone who'd like a little extra help to stay cool in summer.
