fan duct semi circular

thingiverse

I constructed the initial design, which successfully resolved my issue, thank you for assembling it. However, I had to add an extra block section to the front so it could snugly fit in place as desired and I believe I also shortened it slightly; I made no alterations to the duct's interior whatsoever. This device is currently being utilized on a custom corexy gantry setup that I have created.
