Adjustable Semi-Circular Anet A8 Fan Duct

I've taken notice that with the standard fan duct, the walls are remarkably thin. I've included a few alternative models - one with an additional 1mm and another with a 3mm increase in thickness - allowing you to precisely position the fan duct as close as possible to the print itself. This thoughtful addition will undoubtedly earn my gratitude later on.
