This is a custom Ender 3 S1 hot end that uses two 5015 blower fans.
Print orientation as shown in photo. Only supports necessary on the build plate. PLA is fine, I've been using this for about half a year without any issues. If you do get warping or melting use a more heat resistant filament.
SolidWorks file included to edit the part. (Not easy)
