5020 Fan Blower Mount - Creality Ender 3 V3 SE

This replaces the stock 4010 Fan with a 5020 Blower.

=>>> Significantly less noisy than the stock cooler <<<= Pushes more air, but be advised, noise level will increase.

You'll need (2) M3x20 Flatheads with Nuts, or M4 heatset inserts + Flatheads to mount the Fan and the original (2) M3 Flatheads to mount the Shroud.
