Yes, all the Hero Me parts for an Ender 3, using all stock parts (4010 radial fan and 4010 axial fan), are in the correct orientation for printing. Note that there will be a new Gen3 version of the single 4010 OEM cooling duct posted later this week. The Gen2 version of the cooling duct will work fine on the Gen3 Hero Me base.
