This simple fan duct directs air to the hotend.
Especially designed for Prusa i3 with MGS extruder, can be easily adapted to other printers.
Inspired by b2x fan duct, I designed a much simpler one, with a very simple OpenSCAD file you can easily modify.
Print the uploaded STL file.
Use OpenSCAD file if you want to make any modifications. Hotend fan duct
