FLSun delta part cooling adapter for centrifugal fan
cults3d
My 2017 FLSun delta came with a rather anemic centrifugal fan for the parts cooler. There are other adapters around (like https://www.thingiverse.com/thing:2369318 and https://www.thingiverse.com/thing:2477073), but they all use axial fans. I felt like a centrifugal fan was the better approach, so I designed yet another fan shroud myself. This was designed for the 2017 "New effector", using a 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 think most (if not all) 4020 blowers will work. Greatly reduces warping and sagging, but I have noticed a slight increase of rippling - possibly due to the added inertia. Does not collide with the delta arms on my "large linear" printer. Combines very well with https://www.thingiverse.com/thing:2251745
