Adapter 5010 to 4010 (Ender 2 PRO mainboard fan)

I changed my fan from 5010 to 4010. And changed the hotend fans. I have made so 12dB quieter (All fans on 35dB).

Description

The shape has a venturi effect. This allows more air with the same power.

I hope you can also use this.

Matierial:
You need 2x M3 nut and 2x DIN 912 cap screws M3x20

As always, I wish feedback for continuous improvement.
