I modified the bullseye duct to use Dual 4010 fans. Because that is what i have. Dual Ball bearing high speed 4010 fans.
I did this because i added the Ender 3 (v1) direct drive kit to my v2... it was way cheaper than anything else.. and this is the one that would fit in that scenario.
Also i have Dual Z motors on my ender 3.. using direct drive i haven't seen any addition wear on my rollers.. But.. For anyone that questions it.. dual Z on an ender 3 really just splits the torque between the 2 motors.. so you get one really strong motor or 2 weak motors... Dual Z is only saving my rollers because i don't have to run them so snug to the z-rails to prevent sagging.. The ender 3 z driver only puts out like 110% max of one z motor... adding a second one.. if you crank the vref to 100% rated it just overheats and cuts out...
