CR10s Control Box Cooling for Enclosure (120mm Fan)

I designed this to keep the control box for my CR10 from overheating in an enclosure. I printed the CR10 legs to be able to set the control box under the printer. This is an intake to pull fresh (cool) air from underneath the enclosure. It is designed to install a 120mm fan (air flow direction is critical). The fan works as a booster. The CR10 control box gets cold air from the vents on the left side of the box. The 2 case mounted internal fans are exhaust fans. I am using an all-metal computer
