FLSun delta part cooling adapter for centrifugal fan

thingiverse

My 2017 FLSun delta came equipped with a rather underpowered centrifugal fan for the parts cooler, which left much to be desired. Fortunately, there are other adapters available online, such as those found at Thingiverse (https://www.thingiverse.com/thing:2369318 and https://www.thingiverse.com/thing:2477073), but these designs rely on axial fans instead. I believed a centrifugal fan was the superior choice, so I designed another custom fan shroud myself. This design is specifically tailored for the 2017 "New effector" model, utilizing a powerful 4020 centrifugal blower (https://www.aliexpress.com/item/Blower-cooling-Fan-40mmx40mmx20mm-DC-12V-2-Pin-Brushless-Cooling-Cooler-Centrifugal-Blower-Fan-4020/32828068985.html). However, I am confident that most (if not all) 4020 blowers will be compatible. The results are a significant reduction in warping and sagging, although I have noticed a slight increase in rippling - possibly due to the added mass. Thankfully, this design does not collide with the delta arms on my "large linear" printer. This adapter combines perfectly with another popular design found at Thingiverse (https://www.thingiverse.com/thing:2251745).
