This fan shroud is designed around the MKS Gen 1.4 board, and is designed to cool the stepper drivers using a 60mm fan. The shroud is mounted on the board by using a 20mm hex standoff (shown in yellow in the pics). Its designed to minimize the need for re-routing cables and should be easy to install/remove.
Supports are required when printing in either orientation. I recommend a wide nozzle and extrusion width due to the shallow pitch of the slopes on the shroud, and 3-4 perimeters.
