Geeetech Prusa i3 Acrylic pro B - 50mm radial fan duct

I made this fan adapter as none of the existing radial ducts was fitting my printer.
With the adapter you can move it up/down/left/right for exact positioning.

To assemble you need 2xM3 to attach the adapter to the extruder mount an 2xM4 screw + 4xM4 nut to attach the fan to the adapter.
