Round to Square AC Adapter

This is a remake of someone else's design. I'm sorry I could not find the original. Happy to attribute if someone can point me to it. Essentially I just used tinkercad to add some larger circles until it was wider than I needed, then I duct-taped it to the exhaust hose #fancy.

I wanted to mount the exhaust hose for my air conditioner AC unit to a thick piece of wood to prevent heat/noise transfer. I use this on a base floor window, so the wood has the added benefit of making it much more secure. It's really easy to push in those flimsy plastic window fillers that it comes with. Additionally, doing it this way allowed me to mount the exhaust hole much lower on the window filler, allowing the blinds to come down almost all the way.

I printed in PLA with Support (touching build plate). I printed with square side down.
