Fan duct and matching fan grille for mounting a fan directly above a MKS GEN_L board. When used with a thin fan (8010), the design fits right inside the JGAurora A5 with enough headroom for the Y-axis gantry to pass over.

Orient the cable to allow for easy routing to the power supply or board connector. One after the other, replace the bolts mounting the MKS GEN_L board with the hex spacers. Make sure they provide enough room for the fan holder plate to pass over the driver heat sinks. Mount the fan holder assembly with M3 bolts and connect the fan.
