Tevo ventilator grill

I used three Ikea Lack tables to make my enclosure. The third table top was fitted as a shelf below the printer to mount the power pack, mosfet and spool carrier. I then fitted panels to the sides to be tidy. The power pack and mosfet need ventilation so I created this ventilator grill to allow air flow while restricting access. I couldn't be bothered cutting a complex shape into MDF and so this grill will push fit into a simple triangular hole. Other uses also will be valid!!!
