Wanhao Duplicator i3 Plus MK2 rear attached Cooler (with Proximity Switch)

thingiverse

I've been on a mission to find a Fan Duct that doesn't obstruct the front view, and I finally couldn't find one, so I decided to take matters into my own hands. The design is specifically tailored for the Wanhao Duplicator i3 V2.1, which features a proximity sensor, resulting in an offset bracket for the fan on this model. To ensure you have the correct model, I've included a photo of the box where the printer came in. Additionally, there are photos of the fan duct on a green mat, which is my test piece and not the final product, so please note that the print quality may not be up to standard. Lastly, I've attached a picture of the fan installed, highlighting the proximity sensor, vertical plate, and most importantly, the unobstructed view from the front, which was the primary objective of this project.
