For those of you asking for an Ender 3 "PRO" Bullseye duct to fit the wider attaching points for the 4010 fan on the PRO, here's what I've got. It should accommodate the extra width nicely. The file is: Ender3ProBullseyeDuct10.19 Dave 2/25/20 A user messaged me that this will also fit the Cr10 Mini which uses the same fan as the Ender 3 Pro. Print with 4+ walls with 50%+ infill. These are structural parts and need to be strong, especially the mounting points. This shows the narrow directional airflow with low pressure air exhausting the "used" hot air to the back of the build plate. This provides a constant fresh airflow on the filament. It also shows why I suggest you mount your duct outflow ports just below the insulation. Here is the CFD V Trace for the Bullseye. You can see in the smoke generated video that it matches the the airflow simulation as anticipated.
