K8200 Cover and plate

Made a new cover and baseplate for the electronicboard for the velleman K8200. Its a slide cover with ventilation holes and hole for the usb.Can't pull the connector for the usb off this way.
Red light from the board lights up the cover a bit :).
The holes for montage up and bottom are 6mm DIA and the 4 other holes for the board are 4,6mm DIA
