Fan bracket 3d Builder for single extruder

The original mount of the fan, of my big builder single extruder was not really working or looking great. So I designed a new bracket which works perfect with my own design fan guard.

You need two small, M3 screws for the mount to the metal bracket.
And I used 4 M3 20mm Stainless steel bolts.
Like the photo shows.
