Anet A8 40mm fan part cooler
thingiverse
Original fan started to make noises so I made a mount for an axial 40mm fan. Duct can be printed without supports if turned upright on its "feet". (Brim recommended.) Try to find a small but powerful fan, I made some stator vanes to try to improve static pressure. Versions for m3 and m4 fan bolts, also stator vanes both counter-clockwise and clockwise. Printer must be tuned since parts must friction-fit together. Printed with 0.2mm and 20% grid infill. 2020-05-21 - Revision 1: It's a bit rattly. But works quite well (a bit less fan speed needed for the same bridging result as the classic semi-circular version with stock blower). Made a reinforced version of the mount that hopefully will get rid of the rattles without increasing mass too much (rev1 parts). Fan I used: Sunon EE40101S1-1000U-999
