Right lid w/fanduct for Teaching Tech Ender-3 universal rear el. case.

I have fitted Teaching Tech's Ender-3 Universal rear electronics case (which this is a remix of). With my MKS GEN-L motherboard I had the trouble that the stepper drivers were extremely hot. It seems in my setup there are too many air-gaps for the air to be pulled across the electrical boxes, as intended.

So I whipped this thing together. I grabbed a fan (EBay link below) I was not using and tried to make something out of the right lid, without colliding with the stock mounted Y stepper motor
