Ender 3 40x40mm Cooling fan attachment
thingiverse
Upgrading my Ender 3, I didn't like the choice of the blower fans for part cooling, so I made an attachment to hold a 40x40mm fan, the same as what I used for the Hotend cooling. I used a 10mm thick fan, you could use a 20mm fan if you wanted. I used the same 4 mounting bolts the stock fan used, but I had to cut them slightly shorter (I used pliers, they're not very strong) otherwise they would hit the other fan inside the metal cover. It sits slightly off center so it doesn't hit the X belt tension bracket. I also made an additional air flow support to fit this which can be found here: https://www.thingiverse.com/thing:4459778
