wanhao 4s Front Fan Brackets

as we all know printing in PLA is aided by better airflow to cool the plastic as it's laid down. this improves the quality of prints. Well, i didn't want to start soldering extra fans onto the motherboard of my shiny new Wanhao 4s. so i came up with this cheap solution. 2x usb desktop fans off eBay.

The fans are removable as they sit on dovetail joints.
