This laptop stand is designed to perfectly fit the Alienware X15 R2 chassis. It's solidly constructed, easy to transport and ideal for use on the go. It does not cover any of the top ports (audio jack and charging) and allows full freedom of movement for the lid. It also doesn't cover any of the engaging and ejecting skirts for the fans. Both f3d and step files are supplied along with STLs for easy modification if needed.
