5020 Air Ring for Ender 3/5
thingiverse
I created these air rings to use with 5020 fans on my Ender 3Pro and Ender 5Plus, the models are different in order to centre the nozzle on the 2 different machines. I found the stock fan is kinda weak, tried using 2x 4010 or 2x 5020, IMO best it to use 1x 5020 fan is as strong as 2x 4010, which is double the CFM of the stock fan, and it takes up less room and lighter-weight. I used Resin printer to print the air rings to withstand heat but you can use other filament. SLA is not recommended because it tends to deform when printing ABS/PETG with fan off.
