Ender 3 direct mount bmg aero wind al-bmg fan support + bltouch

thingiverse

I made some adjustments to the design because they didn't fit perfectly. The 40mm fan bracket required M3x45mm screws, but since they're hard to find, I reduced the depth slightly to adjust it to M3x40mm. Since the layer fan was positioned very low and rubbing against the base, I created a support adjusted to the necessary height and made it slightly thicker because when in contact with hot metal it deformed due to its narrowness. I modified the layer fan nozzle to 45 degrees so that it wouldn't interfere with the extruder lever and be able to open it if there's a jam without having to disassemble everything. Version 2.0 I modified the design of the aluminum block bracket to maximize cooling, allowing you to use the bmg screw holes. To mount the bracket, all you need are M3x50mm screws; I couldn't find them but made custom screws with an M3 threaded rod and a nut glued with superglue for the head. To secure it, I cut a slot for a screwdriver, making it perfect.
