Wanhao Duplicator I3 Controller replacement backplate

The initial batch of Duplicator I3 units could use some extra air intake on the controller. There are air vent holes but no intake holes (at least on my unit). This is a replacement back plate that can be laser cut out of wood or plexiglass or 3d printed. There are two openings that can be left open to allow for air intake or you can install one or two 40mm fans to suck air in to help circulate the air over the power supply and board. The power supply does have a fan that pulls air in but there still needed to be a source for the air.
