Adapter, Blower Fan Mount, 5015 replacing 4020

thingiverse

This is a simple mount adapter intended to allow for a (somewhat) drop-in-replacement of a 4020 blower-style fan with a 5015 blower-style fan. In my case, this 5015 fan was replacing a dying 4020 fan used to cool the mainboard in the bottom of my Creality Ender-6. The replacement 5015 fan is attached to the printed plate with appropriate hardware; then, the plate is screwed into the place of the original 4020 fan using the threaded screw holes and screws of the original fan. Thus, all that should be required to replace a 4020 blower fan with a 5015 blower fan (presumably, of same voltage) - assuming there's enough clearance - is this printed mount/adapter and two screws with accompanying nuts. I used two "round-head, #8-32 x 1 inch" machine screws to attach the 5015 fan to the printed adapter. I'm not sure of the metric equivalent, since they weren't readily available to me; but, it's probably M3 or M4, and you'll need them to be about 20-25mm in length, I think. *Note:* it is assumed that the 4020 blower fan was originally screwed into standoffs of some sort, rather than being attached flat against some surface, or that there there is at least some amount of open space between the fan's body and the nearest surface, such that there is room for the screws/nuts. See the last picture in my assembly instructions, below, which shows the need for some amount of clearance in my use case. *Print Settings:* I printed this on my Creality Ender-6 with eSun PLA+ Black filament at a layer height of 0.16, no supports or brims, and probably 15% infill. It's a pretty simple design, so there's no special requirements for how to print this, really. You'll know what works best for your printer. You'll just want to make sure the screws can fit through the holes - certain settings regarding resolution or tolerance may affect this. *Cross-posts:* *[Printables](https://www.printables.com/model/551148-adapter-blower-fan-mount-5015-replacing-4020), [Cults3D](https://cults3d.com/en/3d-model/tool/adapter-blower-fan-mount-5015-replacing-4020)*
