Ender 3 (+CR10?) Fan Duct Ring

thingiverse

Added an extra model with bigger slots for better airflow to the nozzle. I really like the design of the Fan Mount by nghtshd which just fits straight on the original extruder housing, but the duct wasn't what I was looking for, I like when parts are cooled all around. So I modified the fan duct ring made by Filboyt together with the duct from nghtshd into 1 additional nozzle that slides into the Fan Mount. The fan duct from Filboyt wasn't working well with my stock fan and I wanted to use a 5015 fan without all the complicated mods. The modified duct slides into the fan mount from nghtshd and is fixated with a screw. Its not so well fabricated as I would love, my 3d designing skills are limited (by time and patience) and I used only Tinkercad for this. Feel free to try this (at own risk), works fine on my two E3's.
