4" duct to rectangle duct (addons coming soon)

thingiverse

I rerouted the AC vent in my office under my desk, since working from home while 3D printing can sometimes get hot, especially when two computers are running at once. To stay cool, I wanted a more direct airflow, so this is the first part of a setup that will continue with additional components. Next, I'll be adding a splitter and all necessary connections to complete the system. I'm also planning to include a shutoff feature for when winter arrives, as I don't want to risk freezing myself out. Below is a version with supports generated in Meshmixer; they worked flawlessly, so I highly recommend using that exact configuration.
